The change of residual electrical resistance during isochronous and isothermal annealing of non-saturated solid solutions of Cu—Al, Ag—Al, Fe— Al, and Ni—Cr in a wide range of concentrations and with various initial states (deformed at 77 and 300 K, quenched from various temperatures, and annealed with a slow cooling) is studied in a given work. The investigation of short-range order is carried out for specimens of Cu—Al, Ag—Al, and Fe—Al alloys after same treatments by the method of X-ray diffuse scattering. As shown, the residual electrical resistance and absolute intensity of scattering, and hence, the Cowley’s short-range order parameters have the complicated change during an annealing. As suggested, the short-range order in these solid solutions is inhomogeneous. Not only the short-range order degree, but also its type determines the change of residual electrical resistance. The uniquely defined correlation between the residual electrical resistance and the short-range order parameter for the first co-ordination shell, $\alpha_{1}$, is absent for wide ranges of temperature and concentration.
Keywords: solid solution, short-range order, residual resistance, X-ray diffuse scattering.
