Abstract

Present investigation pertains to establish the bulging characteristics of sintered steel preforms under cold upsetting. Cylindrical preforms of Fe-0.8%C and with 1%Mo and 2%Mo of 86% initial theoretical density and 0.4 initial aspect ratio have been produced through conventional powder metallurgy techniques. These preforms were further subjected to secondary deformation, that is, cold upsetting under nil and zinc stearate lubricant conditions. The results obtained from this experiment were used to study the bulging characteristics with densification and hoop stress. An empirical equation is determined between these parameters and is found to follow a power law relationship.
