Titanium And Titanium Alloys Engineering Essay
Titanium And Titanium Alloys Engineering Essay Material selection in manufacturing process is an important stage because proper selection of material not only can prevent catastrophic events from happening, but it allows a product to be manufactured in an efficient and effective way at low cost while meeting product performance objective. In this assignment, we are going to research into two material topics and identify the usage of these materials and overview some of the properties as to why they are chosen for specific application over the others and manufacturing processes. Topic1: Titanium and Titanium Alloys 1.1 Applications of Titanium Alloys Titanium and its alloys are widely used in variety of areas. These areas include aerospace industry, marine operation, automobile, bio-medical applications, etc. Figure 1: Applications of titanium alloy 1.2 Automobile Connecting Rod One application of titanium alloy is applied in producing connecting rod for automobile in order to achieve high performance for high end racing vehicle. Connecting rods are one of the most important automotive components as it responsible for changing the reciprocating motion of piston into rotary motion so that the power generated by the chemical energy can be transmitted from piston to crankshaft and finally producing forces driving the vehicle. 1.3 Material Properties require for Connecting Rod Weight is always an important factor to consider in racing sport competition, therefore in racing sport arena, car builders always try to reduce the overall weight of the vehicle so that every single drop of power generated by the engine can be utilized in providing motion for the vehicle rather than carry its own weight. This result in many of the car components are replaced by materials which are light, robust without compromising other materials properties like tensile strength, compression strength, damping capability, creep, fatigue, etc. This includes the connecting rod for the engine. The weight of the connecting rod is important because it influences the performance of the engine is terms of forces generated and response of the engine. If the connecting rod is made lighter, it is usually better as less weight enable the throttle action and acceleration can be carry out more smoothly and effectively, thus enhance the engine efficiency. However, strength and other aspect of mat erials properties are equally important owing to the reciprocating load generated by the movement of piston inside the cylinder and crankshaft. For every revolution of engine rotation, the connecting rod is under huge amount of compression and tensile forces. Hence, it is necessary that the connecting rods strong enough to handle all the power produced by the engine and withstand all the forces that tend to pull the rod apart during exhaust and crumble the rod during compression which results in irrepairable engine failure. Since the engine is operating at high temperature and needed to sustain a sudden force caused by the explosion of chemical happen within the cylinder, as a result it is very important that connecting rod possess high fatigue strength, high fracture toughness at elevated temperature, high shock resistance, etc. Summarizing the needs for connecting rod, materials properties requires for a connecting rod include: High strength to density ratio Low density Low thermal expansion High fatigue strength in elevated temperature High fracture toughness in elevated temperature High shock resistance Low ductile-to-brittle transition at low temperature High melting point 1.4 Manufacturing Processes of Connecting Rod In general, connecting rods are produced by conventional forging method Figure 2: Conventional Forging Manufacturing Processes for Connecting Rod 1.5 Conventional Forging Method 1.5.1 Material Titanium is extracted from titanium ore by Kroll Extraction process follow by blending, melting, casting, forming and heat treatment to produce the required material for connecting rod. 1.5.2 Cutting to length of material The material is cut to the length near the final end product. 1.5.3 Billet Heating Alloy is heated to make it malleable prior to forming operation. 1.5.4 Hot Forging Red hot alloys which are in plastic condition are shaped into connecting rod by using compressive force. The alloys gone through the heating process is placed into die block and compressive force is imposed on the material by a hammer to strike it into the shape of connecting rod. 1.5.5 Trimming After the forging process, the ledge of excess material is removed by trimmer machine. 1.5.6 Piercing The material in the center of the holes is removed. 1.5.7 Shot Peening Shot peening is used to produce a residue compressive force to modify the mechanical properties of the surface to further improve the fatigue resistance. 1.5.8 Machining Machining process include deburring, milling, grinding, polishing, drilling, boring and inspection are carried out to produce the final connecting rod. 1.6 Advantages and Disadvantages of Titanium Alloys 1.6.1 Advantages of Titanium Alloys High strength-to-density ratio allows titanium alloy to replace steel and other materials in many areas. Figure 3 and 4 reveals the superior structural efficiency of titanium alloys compared to other alloys, especially as service temperatures increase. Figure 3: Structural Efficiency at Elevated Figure 4: Density Comparison for various Temperature Metal Specific Strength of Titanium Alloys is generally higher than any other alloy at elevated temperature. Figure 5: Specific Strength for several alloy at elevated temperature Titanium alloys have better fatigue strength than other lightweight alloys. For instance, aluminium, magnesium, etc. The corrosion resistance of titanium alloys also far better than steel and even aluminium alloys. This enables titanium alloy product suitable to be used in caustic environment. The high reactivity of titanium with oxygen enable immediate forming of oxide layer which protect the material from corrosion. The primary reasons why titanium alloys are attractive materials in many areas is because it exhibits excellent strength to density ratio, low density and corrosion resistance. Other aspect of material properties including the following: High fatigue strength in air and chloride environmentsà High fracture toughness in air and chloride environmentsà Low modulus of elasticityà Low thermal expansion coefficientà High melting pointà High intrinsic shock resistanceà High ballistic resistance-to-density ratioà Nontoxic, non-allergenic and fully biocompatibleà Excellent cryogenic properties 1.6.2 Disadvantages of Titanium Alloys Titanium extraction process is difficult and expensive. Titanium alloys have much higher flow stress than Al alloys or steels, thereby requiring much higher forging pressure capacity. Titanium and its alloys are more difficult to machine especially beta phase titanium alloys in comparison with steels and aluminum alloys for conventional methods such as milling, turning, drilling, etc. Titaniums has low thermal conductivity which reduces heat dissipation at the metal work-piece interface causing tools lifetime reduce and decreased welding or galling at tool and work-piece interface. 1.7 Structure and properties Titanium alloys are classified according to the amount of alpha and beta resides in the structure at room temperature. 1.7.1 Alpha titanium alloy The single phase alpha inhibits the heat treatment process. However it ensures weldability of the alloy. The strength and corrosion resistance at elevated temperature for alpha titanium alloys very much dependent upon the Aluminium and Oxygen element in the alloys. Figure 6: Ti-5% Al-2.5% Sn alloy in sheet form Figure 7: Commercially Pure Plate,0.03% iron Air cool at 732C/30Min 1.7.2 Alpha beta titanium alloy Beta stabilizing element results some beta phase to persist below the Beta Transus temperature which leading to two phase system. Two phase system enable Titanium alloy to be strengthened by heat treatment for example quenching, annealing, aging. Figure 8: Titanium Phase Diagram Figure 9 :Ti-6AL-4V Alpha-beta alloy plate air cool at 788/15 min 1.7.3 Beta titanium alloy Beta titanium alloys possess Body Center Cubic, BCC crystal structure is readily cold worked in the beta phase field. This allows solution heat treating follow by quenching giving high strength for the alloy. Figure 10: Ti-13V-11Cr-3AL alloy solution heat Figure 11: Flow stress for Titanium alloys treated at 788C/30min and water quenched Topic 2: Ceramic Coating 2.1 Ceramic Coating and Application Ceramic coating is one of the coating techniques developed for spraying ceramic material on the surface of object of interest to further improve the mechanical and physical properties for a readily available product made from certain materials so that the component life can further be extended. The typical application of ceramic coating is applied to create the thermal barrier for gas turbine engine blade, exhaust system, intake manifold and reduces the surface friction between two different materials to improve the wear resistant as well as making the interface between two materials more compatible. 2.2 Automobile Exhaust Manifold Exhaust manifold serves as a system to vent the exhaust gases away from an engine so that new round of cycle can begin. In automobile, we always wanted the engine to perform work with as high efficiency as possible, however most of the conventional exhaust manifold is usually made from cast iron alloy and other material. These materials usually having good thermal conductivity. This is not preferable because high heat dissipation rate can contribute to loss of energy which reduce the efficiency of the engine. With ceramic thermal coating applied on the exhaust system, engine performance improves in a number of ways. Firstly, they protect the exhaust system from rust and corrosion. Secondly, they reduce heat loss which can be translated into engine output. This can be viewed from several aspects. Ceramic coating insulates the heat of exhaust gases from the environment thereby keeping the exhaust gases hot which allow the gases flow more smoothly and these aids in cylinder scavenging. Next, by retaining the hot exhaust gases in the system, it reduces the engine bay temperature which results in intake air temperature reduced. Drop in intake air temperature can lead to less fuel usage and therefore increase the engine efficiency. For vehicle with turbocharger installed, the hot exhaust gases allow the turbocharger spool up more quickly making the engine more responsive. 2.3 Processes for Ceramic Coating 2.3.1. Surface Cleaning Before the manifold surface receive the ceramic coating, degreasing chemical would be used or material would be heated to high temperature to remove or burn off any foreign particle exist on the surface. The manifold will then be place in the oven at around 450 for around half an hour. 2.3.2 Coating Ceramic coatings are mainly manufactured by using atmospheric plasma spray method, APS. APS using the strong electric arc that generated between a positively charged electrode and negatively charged electrode to ionize the flowing gases into plasma state, then followed by injecting powdered ceramic into the plasma jet in order to melt the powder materials and propelling them onto the work-piece surface. This process allows the metal substrate to be coated with ceramic leaving a smooth protective layer. Figure 14: Atmospheric Plasma Spray Coating Technique 2.3.3 Finishing The manifold is then allowed to air dry for around 20 minutes before placing it in the oven to set the coating. Once it has bakes, the manifold is polished with a steel wool brush. 2.4 Advantages and Disadvantages of Ceramic Coating 2.4.1 Advantages of Ceramic Coating Ceramic coating protect the metal surface against rust and corrosion which extends the components life Ceramic coating create thermal barrier which reduces heat lost which enhance the engine performance and reduces the engine bay temperature. Ceramic coating can sustain high temperature up to 1100 which make it suitable for high heat application in aerospace as well as automobile industry. Ceramic coating can survive bending and shock without crack, peel or forming chip Ceramic coating comes in a variety range of colour which in turn improves the aesthetic for the component. Ceramic coating can be removed easily 2.4.2 Disadvantages of ceramic coating ceramic coating can be a costly process uniformity of coating thickness can be quite difficult to maintain might be difficult to apply to complex shape component owing to inside corned can have low film thickness according to Faraday Cage Effect 2.5 Microstructure of ceramic coating by Atmospheric Plasma Spray, APS Figure 15: (a) (b) Microstructure of ceramic from literature (c) Ceramic microstructure with thichness measured.

A Jury of Her Peers by Susan Glaspell Essay -- A Jury of Her Peers Ess
"A Jury of her Peers" was written by Susan Glaspell in 1917. This short story is entertaining but also tells the story of women in the early twentieth century. Ms Glaspell give you an idea about the hardships that women had to deal with, such as loneliness, lack of beauty, physical labor, and living in a male dominated society. The characters consist of two couples and a lawyer. The men are trying to convict Minnie Foster of murdering her husband while he was sleeping. The story takes place in Minnie's house. Throughout most of the play the men ridicule the women. This is ironic because the women are the ones that end up finding the missing link to the killing. Throughout the play the men are looking for evidence that would give Minnie a motive for the killing her husband. The men look everywhere for evidence; as they do this they poke fun of the women. The men just do not understand the hardships of being a woman at the turn of the century. Loneliness was a major factor for farmwomen in the early part of the century. Elaine Hedges quotes Faragher's statement saying "the single most important distinction between the social and cultural worlds of men and women was the isolation and immobility of wives compared to husbands" (Elaine Hedges 99). The isolation of the houses contributed to the loneliness women felt. The farmhouses were miles apart and could take up to half a day just to visit a friend. Women did not have time in their busy schedule to take such trips. Women were preoccupied with household chores and running the family. The men could combat loneliness because they had the advantage of going into town with the crops. At these visits they could catch up on the news as they sat in the saloons with the gu... ...ause none of them were small. To can fruit there is a lot of effort involved. The fruit must be grown, picked, and still canned. Ms Hedges informs her readers of the physical labor involved by quoting old diaries, "Friday May 27 This is the dreaded washing day" (Hedges 96). One must not forget that there was no running water back then. One load of wash took tremendous amounts of labor: "One wash, one boiling and one rinse used about fifty gallons of water -- or four hundred pounds -- which had to be moved from pump or well to faucet to stove and tub, in buckets and wash boilers that might weigh as much as forty or fifty pounds" (Hedges 96). This reason alone explains why Minnie is worried about her jars while she is in jail. As one can see "A Jury of Her Peers" was not only written for entertainment, but also to demonstrate how rough life for farmwomen was.
Ethical Issues and Issues of Sensitivity in Sociological Research Essay
Ethical Issues and Issues of Sensitivity in Sociological Research Ethical issues are the considerations that can have an important influence on the research process. They are moral principles- beliefs about what is right and wrong, which often guide research. Sociological associations in many countries have a set of ethical guidelines for conducting research. There are six main ethical issues; I will explore them below. Sensitive issues are issues that need to be dealt with tactfully because of their subject matter. This could include subjects such as death, health issues, sex etc. These are potentially sensitive subjects as the people being researched may have had an unpleasant situation with them. The first ethical issue I will investigate is "informed consent". This is the idea that those the researchers are studying should be given the opportunity to agree or refuse to participate in the research. This means covert observation could not take place, as this involves not letting people know they are being observed. Informed consent means that the researcher must provide information about the aims of the research, what the conduct of the research involves and the purpose to which the research will be put. This issue was raised when James Patrick did his research on "A Glasgow Gang Observed". This involved him becoming part of a "gang", only one member of the gang knew he was a researcher undercover. From spending time with the group, he gained information about what they did, what their attitudes were and how far they were willing to go e.g. breaking the law. This research did not involve informed consent, as the majority of ... ...o depends on what sort of person the researcher is, are they highly principled? Or are they willing to cut a few corners to make their research easier or more accurate? How strict a researcher is can definitely benefit/ruin their research. Telling the complete truth to participants about the research could undermine the research or cause research problems, as if the participants know they are being observed it could cause them to act very differently. A lot of issues are not straightforward, some conflict and often need a great deal of thought put into them. To do completely accurate and valid research, the balance between respecting participants' privacy, not deceiving them, being careful not to put them at risk of harm and making sure the data collected is true has to be right, and this is a difficult balance to get.

Republic Act 9211: The Smoking Ban
I wasnââ¬â¢t aware till recently that a smoking ban was being enforced not only in Makati (as everyone generally knows), but nationwide. The Republic Act 9211, also known as the Tobacco Regulation Act of 2003, was signed into law last June 2003 to be in sync with the World Health Organization's Framework Convention on Tobacco Control. The purpose of this act is to protect citizens from the hazards of tobacco smoke, to regulate all tobacco advertisements and sponsorship, to promote a healthful environment, and to assist Filipino tobacco farmers in cultivating alternative agricultural crops to prevent economic dislocation. The Republic Act of 9211 is an excellent law because it doesnââ¬â¢t strip the citizens, smokers or non-smokers alike, from their own perspective rights. In section 5 of this act, the bill states that smoking is prohibited in all public places. This is good because it protects non-smokers from second hand smoking, which is known to cause lung cancer and is very hazardous for the health. This way the health of the non-smoker isnââ¬â¢t affected in any way. The public places where they implement this law are pretty appropriate too like in hospitals/clinics/ health centers /nursing homes because it prevents sick people to get even sicker; in restaurants and conference halls because it allows people to have room to breath in and not die from smoke suffocation; in centers of youth activity like schools because it helps children develop strong and healthy lungs. However, there are smokers who complain about this smoking ban being harsh and that strips their right to smoke. After all, it is their own body that would be affected anyway. The thing is, their right isnââ¬â¢t being stripped at all. The government isnââ¬â¢t banning them from smoking at all. In section 6 of the bill, it states that all enclosed places that are open to the general public, the owner or administrator of such places should establish smoking areas. This means that smokers can still smoke whenever they want but only at specific places so that they wonââ¬â¢t affect the health of others. Smokers have been treated for so long as the minority. We canââ¬â¢t even complain to smokers in the same table or in the same room because we think that that is rude ââ¬â when in truth, itââ¬â¢s the smoker who is discourteous and inconsiderate. This act teaches smokers to be more responsible of their actions and be more considerate of others. It is also written that it is unlawful for minors to purchase cigarettes and for cigarettes to be to them (found in section 9). This point doesnââ¬â¢t need much explaining. We all know that persons under the age of 18 shouldnââ¬â¢t smoke. Since their lungs are still developing, if they smoke, their lungs will grow weaker and it would be difficult for them to breath. Moreover, studies show that people who start smoking under the age of 18 are more likely to get addicted to smoking and it is harder for them to stop. Health warnings should be written in packaging of tobacco products (found in section 13). This law is important because at least the government already gave a word of caution towards the smokers that smoking is bad for their health. This allows the smoker to reflect on their actions and consider the feelings of his family and friends regarding his harmful habit. If these smokers donââ¬â¢t listen and continue, then that is their own problem already. If anything happens to them, they canââ¬â¢t blame anyone but themselves. Right now the Ateneo de Manila University are destroying all smoket or smoking areas located around campus. Without these smokets, there wonââ¬â¢t be a place for smokers to take a huff. I think that the school implemented such a rule in order to prevent students from smoking and start living healthy. However, I think that this action will result to a completely different outcome. Without a place to smoke, the students and teachers would become more agitated and irritated. They wonââ¬â¢t be able to concentrate in class and this would disrupt their process of learning. Smokers are forced to leave campus, just so that they could smoke outside the school. If this happens, there is a high possibility that smokers will come late for class or even cut the entire period. Smoking was never a problem for the school at the first place. Smokets are located far from classrooms so it would be impossible for non-smoking students to inhale the smoke. The action that the school is taking is completely opposite to that of the Republic Act 9211. Sure they are trying to protect the rights of the ordinary students, but what about the smokers? Their right is smoked is being stripped off and I wouldnââ¬â¢t be surprised if a movement that goes against this newly implemented law starts. The implementation of smoking bans has been weak. There are still a lot of places that are not strict in implementation. Nothing much is heard in the tri-media since 2003. And if you go around Manila and the provinces, you would still see a lot people smoking in the prohibited places mentioned. Cities and municipalities that have initiated or intensified anti-smoking campaigns are usually met with strong opposition from the business and the tourism sectors. These sectors say that the ban can drive away tourists and their customers and decrease their income. The Republic Act 9211 may be an excellent law but without serious political will and dedication to have this law properly followed and enforced, it will remain excellent in paper only.
