Heat Treatment and Qualitative Metallographic Analysis Lab ME 3228: Mechanics & Materials Laboratory Summary Comparing a material’s initial treatment and the microstructures that are formed from different processes‚ an engineer can accurately understand why certain treated materials of the same family can be stronger than another. In this experiment annealed and cold-worked specimens of AISI 1018 STEEL are used‚ along with a Hardness tester‚ a grinding and polishing process‚ and a micrograph

1. Introduction The Jominy end-quench test is a technique that has the ability to harden the steel by quenching. It is an essential feature of materials that determine the material’s selection for particular applications. The different types of steels and alloys that are used for hardening in an industry are done by this test and considering that this test is a standardised experiment [1]. 1.1 Aim The specimens that are used in this test are normalized in accordance with the standards. The purpose

During this process while temperature raises it creates a pressure. As it gets confined in anyway‚ the pressure builds up and which becomes explosive. This can occur when the particles of the fuel are divided equally that it forms vapor or dust. Explosions occur in very small confined spaces or where there is high concentration of gases. Importance of collisions between reacting particles: When there are more particles moving in faster speeds‚ more collisions will occur during the short period
