Abstract
The evolution of secondary phase particles in the process of equal-channel angular pressing and subsequent annealing of a Cu–0.6Cr–0.1Zr alloy with an extremely low concentration of solid solution has been analyzed by analytical modeling methods. It is shown (i) that the experimentally observed drop in the electrical conductivity of the alloy during deformation is possible under the condition of fragmentation of secondary phase particles and (ii) that the recovery of the electrical conductivity as a result of subsequent annealing is possible with the additional precipitation of Cr atoms in the form of small particles from the matrix, which is almost completely devoid of alloying elements, and coagulation of the earlier-formed particles.
