The microstructures of TiG0.5N0.5-19%Mo2C-23%Ni alloy sintered at 1723 K in vacuum or in various nitrogen pressures [formula omitted] were mainly studied. It was found that Mo2C phase crystallized during cooling after sintering, when the alloy was sintered in the atmosphere with low [formula omitted], and the amount of the phase increased with lowering [formula omitted]. The phase did not crystallize when the carbon content of the alloy was slightly increased. The reason why the phase was produced or not according to [formula omitted] and carbon content of the alloy was discussed. The transverse-rupture strength of the alloy was examined in relation to these two factors affecting the microstructures.
