The relationship of solid solution carbon and electrical resistivity in retained austenite was investigated by using as-quenched martensitic specimens of Fe-10mass%Ni alloys with added carbon up to 0.9 mass%. With increasing carbon content, the volume fraction of retained austenite increased, and simultaneously, the electrical resistivity of the bulk specimen also increased. Four-types of multi-phase models were applied to evaluate the electrical resistivity of each phase. As a result, the electrical resistivity of retained austenite was found to be increased with the increment of solute carbon concentration monotonously. The dependence of the solute carbon concentration (C-sol) on the electrical resistivity of retained austenite (Delta(rho gamma)) could be formulated as Delta(rho gamma) [m Omega.mm] = 0.26 x C-sol [mass%].
