Abstract

The mechanical properties of TiG0.7N0.3- and TiC0.5N0.5-Mo2C-Ni alloys sintered in nitrogen were studied at room temperature as a function of microstructure, nitrogen pressure (PN2), etc. It was found that transverse-rupture strength and hardness varied in each alloy with changing PN2. As for the strength, the maximum value was obtained at PN2 up to 0.2kPa and at 3kPa in TiC0.7N0.3 and TiCo.5No.5 alloys, respectively. The strength level was higher in the former alloy irrespective of PN2. These results could be understood by considering the fact that pores acting as fracture source were apt to form in each alloy during sintering in nitrogen, but pore size was always smaller in TiC0.7N0.3 alloy; pore size in each alloy was minimized at the above PN2, where each carbonitride was found to be stabilized under these pressures.
