A determination of the stacking-fault energy of some pure F.C.C. metals

Abstract

Abstract A method for determining the stacking-fault energy of f.c.c. materials has been developed using an already-established dependence of preferred orientation on stacking-fault energy. An empirically determined parameter, characteristic of the type of rolling texture exhibited by the metal, is related to the stacking-fault energy value obtained by measurements of dislocation node radius, and from the γ value for the three metals, Ag, Cu and ni the stacking-fault energy of Th, Au, Pd, Rh, Pt and Yb has been obtained by interpolation using measured values of the texture parameter.
