By varying the carbon content, cooling rates, we will get different microstructure of steels that yield different properties which can be tailored to meet different engineering applications. In this experiment, the hardness of 3 steel alloys with varying Carbon compositions will be compared. With different amounts of Pearlite formed, we can also estimate the hardness of pure pearlite and ferrite. Lastly, the fourth sample will be quenched in water and a Martensitic structure will be observed. We

Material Properties of Steel Steel is an alloy of iron, with carbon being the primary solute in the solid solution. It is a polycrystalline solid with grain diameter from 10 to 20 micro-meter (Ashby et al). The presence of impurity like carbon causes the crystal lattice distortions to increase, hence making giving steel better hardness, yield strength, and tensile strength, at the cost of ductility. Pure iron being very ductile but comparatively weak, steel is widely because of its greater load bearing

Name isaiah pryor :D Title my addiction of macaroni cheese Question is have you ever taested anything good but you forget everything about it My obsession of macaroni and cheese.It taest so good that you want to eat it over and over again.All you need is kraft macaroni and cheese,a pot,a spoon,water and (milk) if optional.To me it is the best food I had ever eaten because it is cheesy good. ( Originated from italy ). My advice is eat it whenever you are down because it make

lowers strength and hardness 1, . The microstructure transformation is very complex: Stage1: The formation of transition carbides and lowering of the carbon content of the martensite to 0.25% (100 to 250℃) Stage2: The transformation of retained austenite to ferrite and cementite (200 to 300℃) Stage3: The replacement of transition carbides and low-temperature

Growth of any country depends upon its manufacturing capabilities. Today is world of competitiveness. Every industry must need to increase their performance and reliability as well as quality.Besides this one need to consider cost. Because at last cost will decide whether the thing is of superior quality in that range. So every industry must reduce the cost of process. Every product need to perform different functions as well as under different condition. So product must possess different properties

While cooking a grilled cheese may seem reasonably straightforward, it can be prepared in many different ways, using a stovetop, oven, toaster, or even an iron. The ingredients in the typical grilled cheese can also vary, some examples being the addition of onions, peppers, ham, and mayo. For a standard grilled cheese, all you need is butter, two slices of bread, and sliced cheese of any kind. First, put the pan on medium heat. When the pan has heated completely, take a teaspoon of butter and use

Study of Oxidation of Stainless Steel in Hot rolling Background Studies on the oxidation of stainless in hot rolling have obtained much attention during the last few decades where the finishing temperature ranges from 850-1100 °C. Oxidation is the formation of oxide rich scale that slows down further oxidation when formed. In stainless steels at elevated temperatures (up to 1100°C), this oxide scale is necessary as it is predominantly chromium rich and prevents further oxidation. On the other hand

Introduction Irons chemical symbol eB comes from the Latin word ferrum which means iron. Iron is the second abundant metal and makes up about 5.6% of Earths crust. Iron has the atomic number of 26 and a mass number of 55.845. It’s melting point is 1538°C and its boiling Point is 2861°C. It has a density of 7.874 g/cm³. It is a solid at room temperature and has an element classification of a metal. Irons compounds. Because I am can lose two or three compounds it allows online to make two or
