The stacking-fault energy of F.C.C. metals

Abstract
The determination of stacking-fault energy from the dimensions of stacking-fault tetrahedra is critically examined and the results compared with those obtained by other methods. It is concluded that the dimensions of stacking-fault tetrahedra do not provide a reliable measure of stacking-fault energy. New values of the stacking-fault energy of Ag and Al are used as calibration points for the method of determination of Dillamore et al. (1964) and their values of γAu, γPt, γTh, γPd, γNi and γRh are revised.
