摘要：
A tungsten carbide-base sintered alloy is disclosed, which has a compact three-phase structure consisted of a grain phase of a metal carbide composed mainly of tungsten carbide, a grain covering layer phase of a complex carbo-nitride of titanium and a metal element composed mainly of tungsten in the metal carbide, and a bonding phase composed mainly of nickel and which exhibits very high hardness and high-wear-resistance properties.
