Abstract

Strain hardening of a material is an important phenomenon, which is required to study the plastic deformation of any material and also is an important parameter in the study of workability criteria of metals. The present investigation has been undertaken to evaluate the instantaneous strain hardening behaviour experienced during the cold working of sintered aluminium SiC composites from 0 to 15% under various stress state conditions namely uniaxial, plane and triaxial. Sintered preforms with three different aspect ratios namely 0.38, 0.76 and 1.19 with for different per cent of SiC contents ranging from 0 to 15% were prepared and cold forged. The results were obtained for each aspect ratios and SiC contents at different stress state conditions.
