Effect of niobium carbide on the properties of tungsten-free hard alloys

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

A study was made of the effects of alloying with niobium carbide of the carbide phase of a TiC-Ni-Mo hard alloy (in amounts equal to 2,5,10, and 25 mole% relative to the TiC content) upon the physicomechanical properties of the alloy. It is shown that raising the amount of NbC in the alloy increases its transverse rupture strength (to 132 kg/mm2) and impact strength, leaving its hardness virtually unchanged (91 HRA); the improvement in properties is attributable to a slight increase in the ductility of the grains of the hard phase — a complex TiC-NbC carbide.
