抄録

The carbide powders (WC, VC, Cr₃C₂) having usual particle size of 1-2.5μm were finely ballmilled under a prescribed condition. Using these fine carbide powders (<0.2μm), WC-VC-Cr₃C₂-13mass%Co submicron cemented carbides (VC≤10mass% and Cr₃C₂≤8mass% in binder, respectively) were vacuum-sintered at 1320-1350°C and finally HIP-ed. Microstructures, hardness and transverserupture strength of the alloys were mainly examined.<BR>It has been found that the properties of submicron alloys obtained in the present study are by no means inferior to those of commercially available alloys. It was noted that the ball-milled carbide powders showed a narrow particle distribution, nearly the same as that of commercial powders for preparing submicron alloys.
