Abstract

PURPOSE: To enhance the deflective strength and oxidation resistance of a sintered body by using (MoW)C hexagonal carbide, as hard phase, which has the specified largest value of difference in Mo content between the carbide particles, and adding further Cr, Y or rare earth metals.
CONSTITUTION: Hexagonal carbide obtd. by substituting Mo for part of WC is blended with 3W30wt% of powder of iron group Co or the like as binding metal and 10% or less of one or more out of Cr, Y and rare earth metals, followed by press molding and sintering. The average compsn. of carbide of the resulting sintered body is allowed to satisfy 0≤x<0.8 by mol in (MoxW1-x)C, and fluctuation width Δx between the carbide particles is adjusted to 0.07 or more. Thus, the carbide particles in the sintered body are made about uniform in size, enhancing the quantity of energy to be absorbed in the body and the hardness of the body.
