Effects of hot forging and subsequent carburisation on low-carbon steels.

Abstract

The research intends to work on the increasing hardness of low carbon steels by a congregation of box carburisation with different combination of low carbon steels that have been initially reduced to a certain volume vis-a-vis hot forging.There has not been ample work that look at a combination of hot forging and carburisation and hence this paper is a comparative study of the increase in surface hardness of three metal surfaces at three different steps- when low carbon steels are just carburised; only forged and when the materials go both carburisation and forging. The research is conducted on three different metals(MS, EN8,SAE8620) and Vicker’s Hardness Tester was solicited for hardness testing and conclusions in terms of hardness and case depth rallied with plunge in the volume of the metals.
