AbstractThe sintering behavior of 17-4 PH steel injection molding feedstock was investigated in the temperature range of 650°-1050°C. Effects of sintering conditions, such as sintering temperature and sintering atmosphere, were examined. Experimental results showed that when sintered in a hydrogen/nitrogen atmosphere, the 17-4 PH feedstock oxidized over the temperature range of the investigation. The degree of oxidization increased with the increase of sintering temperature. The main oxidization product was Cr2O3 as revealed by x-ray diffraction and composition analysis. The oxidation can be avoided by sintering in vacuum or argon atmosphere.
