Structure and mechanical properties of composite materials Cu—NbC, obtained by electron beam evaporation-condensation

Abstract

The effect of the strengthening phase of niobium carbide on the structure and mechanical properties of composite materials obtained by electron-beam evaporation and condensation. It is shown that increasing the concentration of the second phase lead to a significant refinement of the grain. The hardness of the two-phase condensates is proportional to the content of the second phase, the density remains almost unchanged. Tensile strength and yield strength increased with increasing concentrations of niobium carbide, plasticity is reduced
