LXX. Anelastic measurements of diffusion coefficients in F.C.C. substitutional solid solutions

Abstract

It is shown in this paper how in face-centred cubic substitutional solid solutions of metals, measurements upon that form of anelasticity which is associated with the preferential reorientation of pairs of solute atoms in the presence of a tensile stress, may be used to obtain the diffusion coefficient of the solute atoms. The method is closely analogous to the one employed recently by Zener and by Wert to measure diffusion coefficients in inter-stitial solid solutions.
