Abstract

Sintering is a key step in the metal injection molding process, which affects the final density as well as the mechanical properties of the sintered part. Densification of metal injection molded 316L stainless steel is one of the hottest research area in recent years. The present study investigates a densification of 316L stainless steel in order to understand the differences in the densification behavior of metal injection molded gas-and-water-atomized powder. Densification of monomodal particle size distribution consisting of fine and coarse powder, as well as bimodal particle size distribution powder for both gas and-water-atomized SS316L is investigated with sintering temperature ranging from 1340 to 1400 °C while heating rate and dwell time remains at 10 °C/min and 4 hour respectively. At the mean time cooling rate was kept the same as the heating rate. Results show that both gas-and-water-atomized powders could be sintered to a maximum of 99 % of theoretical density, which is very close to SS316L’s solid density.
