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

Advanced heat treatment technology can effectively guarantee the quality of products for steel ball manufacturers. Our products are widely applied in metallurgy‚ cement‚ water coal slurry and other fields. Their hardness and corrosion resistance must reach certain standards. With the rising sales‚ the original 8 heat treatment can no longer satisfy the requirements of production. After company leaders carefully studied and discussed‚ the purchase‚ installation and adjustment of new quenching production

Eike Batista Eike Batista was born in the mining town of Governador Valadares‚ Brazil on November 3‚ 1956. The fact that he is the most successful business man in my home country drove me to do a deep research on his history and write this paper about him. Eike is a metallurgical engineer and entrepreneur‚ has business in various areas‚ but especially in the mining and oil field. In 2011 was listed by Forbes Magazine as the 8th richest person in the world with assets valued at 30 billion dollars

Engineering Materials Week 7 10.4 (a) For the solidification of nickel‚ calculate the critical radius r* and the activation free energy ∆G* if nucleation is homogeneous. Values for the latent heat of fusion and surface free energy are -2.53 X10⁹ J/m3 and 0.255 J/m2. (b) Now calculate the number of atoms found in a nucleaus of critical size. Assume a lattice parameter of 0.360 nm for solid nickel at its melting temperature. (116 unit cless/critical nucleus)(4 atoms/unit cell)=464 atoms/critical

Objective The purpose of the Jominy test in this experiment is to determine the hardenability of three types of steels‚ namely EN 8‚ EN 16 and EN 24. Introduction This report will try to illustrate how the hardenability of these types of steels vary and why. This will be done by using the Jominy end quench test on each of the test pieces and then testing the hardness of the particular steel from the quenched end‚ to the end of the test piece. Taking these different points will enable me to find
