Magnitude of the Zener relaxation effect-II. Temperature dependence of the relaxation strength in α Ag-Zn

Abstract

The dependence of the magnitude of the Zener relaxation effect on temperature, T, is measured on polycrystalline samples of α Ag-Zn of three compositions. The experimental results for the relaxation strength, ΔG, are found to obey the equation: ΔG = T0 (T - Tc), where T0 and Tc are constants. This equation, originally derived by Zener, is rederived here under more general assumptions. The quantity Tc, which is interpreted as the critical temperature for self-induced ordering of the alloy, is found to be equal to 175°K, 140°K and 97°K for alloys containing 33.5, 30.2 and 24.2 at.% Zn, respectively. © 1961.
