Abstract

A sintered hard alloy contains at least one refractory nitride and at least one refractory boride or silicide, the total amount of nitride, boride and silicide being at least 55 per cent by weight. The nitride content and the boride and silicide content should each not exceed 10 per cent. The alloy may also contain up to 25 per cent of metals of lower melting point, such as nickel, cobalt, or chromium, and up to about 20 per cent of refractory carbides. Nitrides, borides and silicides of tungsten, molybdenum, titanium, tantalum, zirconium, vanadium, niobium, thorium, and aluminium, and carbides of tungsten, titanium, and tantalum are specified as suitable constituents.
