Abstract
PURPOSE: A hard alloy for powder metallurgy mold, having excellent heat resistance and chemical stability at high temperatures as well as excellent resistance to damage which is manufactured by positively charging oxygen into a specific hard alloy consisting of a hard phase and a high melting metallic phase.
CONSTITUTION: A hard alloy for powder metallurgy mold, consisting of a hard phase and a high melting metallic phase and also having the whole composition of the formula, is manufactured by mixing W powder, a specific metal carbide powder, and a specific metal nitride powder, by drying the mixture, by pressing the mixture in a mold for hot forging, and then by sintering it under vaccum or reduced pressure. In the formula, M1 is one or more of Ti, Zr, and Hf, M2 is one or more of Cr, Mo, and W, a+b is 1, 0.1≤a≤0.7, 0.05≤x+y<0.6, 0.05<x≤0.5, 0≤y≤ 0.5, and 0.1≤z≤0.5.
