Summary:Available data on the temperature, T, and concentration, c, dependence of the critical resolved shear stress, tau , of numerous copper- and silver-based solid solutions have been examined with special reference to the stress equivalence of solid-solution hardening, i.e. a common single curve for all alloy concentrations and solute types in a correlation of Delta rho = tau (78) - tau (298) with tau (78), as first demonstrated by Basinski et al. For solid solutions based on a given solvent metal, the stress equivalence is lost if the value of exponent r in the relation tau (T) proportional to c super(r) varies with temperature. The critical concentration of the solute at which stress equivalence of solid-solution hardening is lost depends on the alloy system.
