By: Bahredin Ali Muzeyin Materials Engineering Department Adama Science and Technology University MAEng3301 October 15‚2013 Abstract Deferent carbon content steel examined to determine the microstructure‚ concentration and hardness of the specimens. 0.2% C‚ 0.4% C and 1.0% C steel specimens were prepared by cutting. Abrasive cutter was used to cut the steels. Furnace was used for heat treatment at 900°C to make the phases separate when seen

3.1 HyperXtrude simulations HyperXtrude is commercial software for simulation which was produced by Altair Inc. It is good at and special for die design and material flow in the extrusion process of metals and polymers. If the simulations are accurate enough for different profile designs and thermo-mechanical behavior of the billet materials‚ it is very important for die designers and production engineers to predict and reduce the cost of die trials. It is of very practical for producing balanced

relationship‚ σT = K(εT)n ‚ where K and n are constants. Finally‚ give a practical process that will strain harden an alloy. c) Thermal processing of a metal allows for the recovery of the initial mechanical properties of an alloy. Describe briefly the recrystallization process indicating the driving force for the process‚ the change in the defect structure of the alloy‚ and the change in microstructure‚ if any. d) Describe a second process which can strengthen a metal. Also‚ explain

PrFan Blades Rolls Royce is unique for its patented manufacturing process of its hollow wide-chord titanium fan blades. To make these fan blades light and strong the fan blades are made from titanium 6-4 alloy with a hollow internal “Warren–Girder” structure. This is done using 2 processes namely Superplastic forming and Diffusion bonding. The manufacture process starts with 3 sheets of forged titanium. A material called stop-off is printed onto 2 of the sheets which will stop them from joining

What metal is said to cause health and environmental problems but it is extremely effective? It is called depleted uranium. Many people ask why we still use it and haven’t tried to replace it. The military actually has done research on alternative alloys‚ but have not found anything comparable. It may have health risks and cause environmental problems. These are counter acted though by its multiple uses that it fills. These uses are found in airplanes‚ ammunition‚ and armor. Depleted uranium‚ also
