Abstract

A theoretical analysis was carried out to predict the deformation and densification behaviour of sintered billets, which are subjected to forging operations like upsetting, sizing, and re-pressing. In each case, a mathematical expression was obtained for the relationship between stress, deformation, and densification; the variables being the initial void ratio and the workhardening characteristics of the matrix material. For each of the upsetting and re-pressing operations, the mathematical equation was computerized assuming the billets to be iron powder compacts having different initial densities. The theoretical results were compared with experimental ones and were found to be in good agreement.
