The interaction processes in the Cr7C3–WO3 system during high-temperature heating are considered. It is established that the resulting powder products are characterized by a multicomponent composition, in which chromium carbide and complex carbides of chromium and tungsten dominate. The properties and structure of these fine-grained powder compositions (master alloys) are studied. It is established that the microstructure of alloyed samples based on powdered iron with the addition of developed master alloys is characterized by high homogeneity and dispersion with fibrous, rod, and lamellar nanoscale carbide formations. The density, microhardness, hardness, and wear resistance of alloyed samples are determined. The effect of developed master alloys on the abrasion wear resistance of alloyed metal matrix composites is established.
