Abstract

A dense alloy is composed of (by weight) 3-50% Mo, 25-95% W and 2-25% Fe and Ni and/or Co, the total content of Mo and W being from 75-98% and the ratio <FORM:0901823/II/1> being between 1.5 and 10. A preferred composition contains 5-20% Mo, 70-85% W, 7% Ni and 3% Fe. The alloy is formed by mixing metal powders (\sO 10m ) in the required proportions, pressing at 5-30 tons/in.2 and sintering at 1400-1475 DEG C. for 5 minutes to one hour in hydrogen or vacuum. The compact may then be slow cooled or rapid cooled, e.g. by transference from the hot zone to the cold zone of the furnace. Specifications 447,567, 497,747, 517,442, 531,117 and 760,113 are referred to.
