The influence of technological factors on physico-mechanical properties and electrical conductivity of copper matrix composite materials

The article was prepared on the basis of the report presented at the 9th International Congress “Non-Ferrous Metals and Minerals-2017”. The influence of the content of the strengthening phase in the copper matrix composite materials of the Cu-CrB2 system on the strength, hardness, and electrical conductivity is described. Presented of data on the change in the mechanical and electrically conductive properties of the material under elevated conditions. According to the macrostructure, the recommendations for reducing the grain size of the composite are proposed.
