This study focused on the effect of Cu powder addition on the densification behavior of SUS304 type austenite stainless steel compacts. The powder mixture were compacted by one axis press at 490Mpa, then vacuum-sintered at 1473-1523K for 3.6ks. As a result, the addition of Cu powder is effective to the densification of the austenite stainless steel, and the maximum relative sintered density (91.7%) was obtained with 2mass% Cu powder addition, sintered at 1523K. Moreover, porosity of the compact was remarkably decreased sintered at 1523K. The hardness of the sintered body increased with increasing sintering temperature, same as density. In addition, remarkable grain growth was not observed with increasing temperature.
