This paper presents an overview of studies aimed at obtaining tungsten carbide alloys with preliminary mechanical activation (MA). MA is widely used in the field of materials science and is aimed at changing the physical and mechanical properties of materials in order to increase the activity of their reaction during research. In this regard, the main attention in this article is focused on the study of the effect of mechanical activation on tungsten carbide (WC) mixtures. WC-based hard alloys are used in various industrial conditions due to their excellent mechanical properties and outstanding wear resistance in combination with high strength and heat resistance, moreover, more than half of the production of WC-based hard alloys is associated with the manufacture of cutting tools. The article also presents complex types of mechanical activation used in various studies. And also considered the effect of the types of mechanical activation of mixtures on the physical and mechanical properties of the obtained alloys. An analysis of the optimal conditions for powder consolidation by spark-plasma sintering (SPS) is carried out, which allows achieving high density and strength of materials.
