FIELD: metallurgy.
SUBSTANCE: invention relates to a nanosized or ultra-fine grain hard alloy and can be used to manufacture tools. Hard alloy includes a tungsten carbide phase with an average grain size from 0.05 to 0.09 mcm, a metal-carbide phase selected from the group consisting of titanium carbide (TiC), tantalum carbide (TaC), niobium carbide (NbC), hafnium carbide (HfC), zirconium carbide, mixtures thereof and mixed carbides of said compounds, and a binding metal phase, wherein the metal-carbide phase other than tungsten carbide is in the form of a cubic crystal structure at room temperature and is at least 4 vol.% in the hard alloy, relative to the total volume of the hard alloy.
EFFECT: creation of a hard alloy with an improved combination of hardness and viscosity.
