Dependence of the Electrical Resistivity on the Degree of Short‐Range Order in Multicomponent Solid Solutions

Abstract The effect of short‐range order on the electrical resistivity in multicomponent solid solutions is studied by applying the model of Rossiter and Wells in which a spherical Fermi surface and s‐s scattering mechanism are assumed. For the description of the state of short‐range order in multicomponent systems a set of generalized Warren‐Cowley parameters α i XY are defined, based on the same assumptions that were used in the earlier treatments of binary alloys, a linear combination between the short‐range order induced resistivity and α i XY is obtained. The possibility of the experimental verification of the derived relationship is further discussed.
