Elevated tribological characteristics of ultrafine grained conductive Cu-0.5Cr-0.2Zr alloy

For the first time, the possibility of radical reduction of the friction coefficient from 0.7 up to 0.3 with an increase in the strength from 950 MPa up to 1600 MPa was demonstrated for electrical Cu-0.5Cr-0.2Zr alloy as a result of the ultrafine-grain structure formation by equal channel angular pressing.
