The effect of oxygen and carbide addition on the sinterability of TiNy(0.42<y<1)-Ni alloys, in which part of the nitrogen is replaced by oxygen was investigated. It was found that sinterability increased as the oxygen and carbide content increased, but the strength of the resultant sintered alloys was significantly reduced due to the presence of Ni3Ti and Ti2O3 phases when the oxygen content exceeded 50 mol %. The sintered alloy with the highest hardness was found when x=0.7, y=0.78 and the (V,Ta)C content was 18% by weight and this alloy was characterized by having a low density, good corrosion resistance and the colour of gold.
