Influence of nickel boride additions on sintering behaviors of injection moulded 17-4 PH stainless steel powder

Effect of nickel boride additions on sintering behavior of injection molded 17-4 PH stainless powder. With increases nickel boride amount, sintering time and temperature, relative density and mechanical properties of specimens increase. Sintering to full density was obtained with the addition of 1 wt.% NiB at 1280 °C for 45 min.
