Abstract

The TiC0.7No.3-14.0vol%Mo2G-(12.0, 16.4) vol%Ni and TiCo.sNo.s-lO.O vol%Mo2C-(12.0, 16.4) vol%Ni alloys were sintered, HIPed and then resintered. The mechanical properties at room temperature and high temperature of 1273 K, and the resistance to chipping and wear during cutting steels were studied for three sorts of alloys, that is, as sintered, HIPed and resintered alloys. The highest transverse-rupture strength and the highest hardness at room temperature were obtained in resintered and HIPed alloys, respectively, independently of the nitrogen and nickel contents. The deformation at 1273K was most suppressed in the HIPed alloys. The results of cutting tests showed that the chipping and wear resistances were excellent in such alloys having high strength and high hardness, respectively. These results were discussed in view of the difference in microstructures among three sorts of alloys.
