Analysis of Cast Iron Machine Parts

Different forms of cast iron are used to make various machine parts like pistons and gears, due to it is castability. It also shows resistance to deformation at high temperatures, even being restorable after damage caused by fire. It is thus important to systematically analyze the various properties of such materials. In this paper an attempt is made to study different machine parts like gears, pistons and ball bearings and their relationship between Rockwell hardness values before and after annealing and their microstructure is analyzed.
