Abstract

Complete experimental investigation on the instantaneous strainhardeningbehaviour of powder metallurgy (P/M) preforms of pure iron, Fe-0. 35%C, Fe-0. 75%C and Fe-1. l%C was carried out. The strainhardeningbehaviour of the above-mentioned P/M sinteredsteel preforms with aspect ratio of 0. 4 under triaxial stress state condition was determined by cold upsetting under nil/no and graphite lubricant conditions. The instantaneous strainhardening value (ni), strength coefficient (Ki), and the stress as a function of strain and densification were obtained and analyzed. Furthermore, a relation was obtained from a semi-log plot of stress against relative density and analyzed to study the hardeningbehaviour owing to densification as stress was a function of induced strain as well as densification in the P/M materials.
