Effect of vacancies on the resistivity of ordered alloys

An analysis is made of the effect of lattice vacancies in a binary ordered substitutional alloy with a bcc lattice on the residual resistivity. A calculation shows that the concentration dependence of the resistivity loses its symmetric form. At certain compositions vacancies can reduce the residual resistivity, and at other compositions they can increase it. An experimental study of the asymmetry of the curve will yield information about the atomic interaction energies in an alloy.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 81–87, September, 1970.
