Abstract

The ultrafine WC-14wt%TiC-8wt%Co (YT14) powders doped different vanadium carbide and tantalum carbide (VC/TaC) content with an average particle size of 270nm were prepared by 72 hours high-energy ball milling. The VC/TaC content was 0%, (0.3VC+0.5TaC) wt%, (0.4VC+0.4TaC) wt%, (0.5VC+0.3TaC) wt% respectively. VC/TaC had disadvantage influence on cubage contraction and density of YT14, but promoted transverse rupture strength (TRS) and refined grain size. When the VC/TaC content was (0.4VC+0.4TaC) wt%, combination property of alloy was best, the density was 11.26 g·cm^-3, the hardness was 92.6HRA, the TRS was 1520MPa, the average grain size was 0.6μm.
