Warm Compacting Behaviors and Sintering Performance of 316L Stainless Steel Powder

Abstract:

Warm compacting behavior and sintering performance of 316L stainless steel powders were studied. Results showed that green density and strength of samples made in warm compaction were much higher than that in cold compaction. Under pressure of 700MPa, green density and strength in warm compaction were 7.01 g•cm^-3 and 30.7MPa, which were higher than cold compaction by 0.19 g•cm^-3 and 10.7MPa. When sintered in hydrogen-nitrogen atmosphere for 60 minutes, sintered density, tensile strength and elongation all increased with the rise of sintering temperature. At 1300°C, Sintered density, tensile strength and elongation were 7.42 g•cm^-3, 545MPa, 28.0%, respectively.
