Experiment 5 - Cold Work‚ Recovery‚ Recrystallization and Grain Growth Objective To study the effects of cold working on the microstructure and mechanical properties of 70/30 Cartridge Brass. Background A small percentage of the energy expended in plastically deforming a material remains stored in the metal as an increase in internal energy. Changes are produced in both its physical and mechanical properties. Principally‚ there is a marked increase in hardness and electrical resistivity with

Abstract This report is to highlight the methods‚ results and theory relevant during an engineering experiment called “cold rolling of metals". The purpose of this report is to show how readings obtained from the set-out experiment‚ can be evaluated to determine the behavior of 3 selected materials; Brass‚ Copper and Aluminium through the process of cold rolling. The form of the materials are in small strips which are processed via cold-rolling method 4 times from their original state to evaluate
