Abstract

The analysis by analytical modeling methods of the experimentally detected lack of sensitivity of the resistivity of Cu-Cr, Cu-Cr-Zr alloys to the structural changes observed in samples subjected to severe plastic deformation was performed. Using the Cu-1.8 wt% Cr-0.8 wt% Zr alloy as an example, it is shown that an increase in the contribution to the resistivity of grain boundaries and precipitated small particles of secondary phases after equal-channel angular pressing is compensated mainly by a decrease in the contribution to the resistivity of alloying elements in the matrix.
