ABSTRACT OF THE DISCLOSURE Refractory. hard carbide alloys intended primarily as replacement for the cast eutectic WC + W2C tungsten carbides currently used as hard components in wear resistant facings, consist of fine-grained and hard two- phase mixtures of subcarbide. (Mo,W)2C, and hexagonal mono-carbide (Mo.W)C. solid solutions, and are formed by solid state decomposition of the pseudocubic.??-(Mo.W)3C2 . or cubic .alpha.-(Mo,W)C?-x solid solutions. The carbide alloys of the invention can be combined with low-melting metal binders to form cemented carbide alloys of at least equivalent wear-resist- ance to alloys using the eutectic tungsten carbides.
