Abstract: The effects of sintering atmosphere and temperature, particlesize of Cr powder, compacting pressure and adding elements (Fe or Co) on the sintering of Cr-Cu alloy are studied. Results show that the density of specimens sintered in vacuum is higher than that in pure H₂ and vacuum sintering has a significant effect on denitrogenation. The density Cr-Cu alloy can be increased by adding Fe or Co. The reason of above effects is discussed and the microstructure, of Cr-Cu alloy is studied.
