Abstract

The effect of sintering atmosphere and sintering temperature on performance of sintering part made of coarse powder was studied.The results show that the performance of sintering part changes along with hydrogen content in the sintering atmosphere.The sintering shrinkage ratio and density increases with the increase of the proportion between hydrogen and nitrogen in the mixed atmosphere,but the carbon content reduces with it;the performance of the sintering part increases first and reduces next with the increase of sintering temperature.
