    superior formability at room temperature. The main features of ductile magnesium alloys are that they have homogeneous microstructure which is free of brittle inter-metallic particles and having uniform plastic deformation promoted by its grain size as well as its crystallographic texture \cite{hirsch2013superior}. Magnesium was even used widely in World War I and in World War II for nuclear and military aircraft applications. Later its usage in military and other applications were reduced gradually. But at present days, due to importance…

  • Chemistry Of Waxing Essay

    Chemistry is a world many of us forget exist in our daily lives. We go about our routines, forgetting that chemistry plays a key role in our lives. As a skier, I noticed the unseen world of chemistry when I am preparing for ski races, waxing my skis. Preparing my skis for a race weekend requires applying multiple layers of wax to my skis. The wax we use is commonly a fluorocarbon mixture. In order for the wax to be saturated into the ski, the block must be melted with an iron. Once the…

  • Al, Alloy 1 And Elece

    time curves and self-corrosion rate of Al, Alloy 1 and Alloy 2 electrodes in 2 M NaCl electrolyte, respectively. Corrosion rates were obtained by weight loss measurements in 2 M NaCl solution after 60 min. As seen in Table 1, the corrosion rate increases in the following order: Al <Alloy 1 < Alloy 2. Fig. 2 indicates that open circuit potential of Alloy 1, 2 (especially Alloy2) is more negative than that of Al. It can be seen that the potential of the Al electrode shifts in the positive…

  • Stainless Steel Case Study

    form the passive layer (described in further detail in the corrosion resistant part). The higher the content used the greater the protection of stainless steel from rust will be achieved. Nickel → steadies the result of austenitic structure formation which enhances strength, ductility and toughness. It also increases the high temperature strength and cryogenic temperatures. It also makes the material non-magnetic. Manganese → also acts as an austenite stabilizer but it also assists in removing…

  • Pros And Cons Of Metal Roofing

    Making The Case For Metal Roofing: The Pros Outweigh The Cons By A Long Shot What your roof is made of makes a big difference in how your home takes care of you and your family. For the following reasons, metal is, more often than not, the best choice for the job. The Pros Of Metal Roofing Longevity A metal roof is likely to remain functional and intact for as long as the home it covers does, resisting weather, rot, infestations and water all the while. According to one industry study, your…

  • Unit 6 Lab

    want to lose or gain an electron is to form an octet, which is to have 8 valence electron in its outer shell. Elements with bigger radius and require less energy to release an electron are more reactive and are able to form an octet easier. I hypothesize that if Calcium is in the lower period compared to the other metals, then it will be more reactive than the other two metals when faced with the tests, and that Aluminium will be the least reactive since it’s located across the group. This can…

  • The Hall-Heroult Process

    This paper will discuss about "the Hall-Heroult Process" history, process, and the two scientists that created this process. The Hall-Heroult process came to be in 1886 in the race of commercially viable route to aluminum by two men working independently, who are Paul Heroult and Charles M. Hall who was assisted by his sister Julia Brainerd Hall. The Hall-Heroult process is the process for smelting aluminum that involves dissolving the aluminum oxide in molten cryolite and electrolysis the…

  • Tungsten Carbide Case Study

    Koutsomichalis et al (2008) discussed that having high hardness and good adhesion with the substrate the sprayed coating exhibited satisfactory wear resistance. Tungsten carbide is an advanced ceramic material combining a unique set of properties such as high hardness, high melting point, wear resistance, good thermal shock resistance, thermal conductivity and good resistance against oxidation. They can be applied as coatings by thermal spraying processes such as plasma-spraying, high-velocity…

  • Executive Summary: Trane Company

    hairpin material in a unit, conversely, only approximately 16 pounds of aluminum. In in the 80’s the cost differential was only 43% or a $22 savings per coil. In 2011, the differential was 79% or $177 per coil. ATI embarked on the development of fabricating aluminum brazed assemblies. We soon learned that making an aluminum braze joint was considerably more difficult that a copper braze joint. Due to this fact the industry placed a small amount of copper tube at the end of the assembly so the…

  • The Pros And Cons Of Ingot Casting

    All metal manufacturing includes a solidification process. The metal is either atomised to a powder, or it is cast. There is several casting methods used today. Many of the methods use the mould only once, for example sand mould casting, the lost-wax method and precision casting. For larger quantities of liquid metal, there are basically two methods: ingot casting and continuous casting. Ingot casting normally uses a permanent mould made by cast iron isolated by ceramic material. There are…
