Study on Mechanical Properties of Carburized Mild Steel Subjected to Heat Treatment

Abstract

Carburizing is one of the known cases hardening method that encouraged formation of carbon layer on the surface of a substance in order to improve the strength and hardness properties. The aim of present work is to improve the mechanical properties of the mild steels samples by using pack carburizing technique. In the present investigation the mechanical behaviors of mild steel carburized at different temperature range of 9000 C and 10000 C are studied. The aim is to examine the effect of these different carburization temperatures and conditions on the mechanical properties of the carburized mild steel. The results of these experiment show that the process of carburization greatly improves the mechanical properties (case depth). Mechanical properties increases with increase in the carburization temperature but apart from this the toughness property decreases and it is further decreases with increase in carburization temperature. The experimental results also show that the mild steel carburized under different temperature range as stated above, with in which the mild steel carburized at the temperature of 10000 C gives the best results.
