Abstract: The work is devoted to the study of electrically conductive properties of metallic materials from the point of view of quantum laws. Methods for describing the influence of various structural factors on their specific electrical resistance are considered. Using the example of the Cu-0.6 wt.% Cr-0.1 wt.% Zr alloy, it is shown that despite the release of alloying elements from the matrix into secondary phase particles as a result of annealing in order to increase electrical conductivity, at the same time the particles themselves can have an increased specific electrical resistance and significantly affect the electrical conductivity of the alloy. This circumstance, in turn, increases the requirements for the composition and volume fractions of the formed precipitates.

Keywords: specific electrical resistance, crystal lattice defects, phonons, secondary phase particles, electron-electron scattering, Cu-0.6 wt.% Cr-0.1 wt.% Zr alloy.
