DETERMINATION OF TWIN FAULT PROBABILITIES FROM THE DIFFRACTION PATTERNS OF F.C.C. METALS AND ALLOYS

Abstract

A new technique is introduced for measuring twin fault probabilities in f.c.c. metals and alloys and is compared to 3 existing methods. The probability of finding a twin fault between neighboring (111) layers is related to the sine coefficients of a one-dimensional Fourier series representing the distribution of power per unit length of the powder reflection. The deformation stacking fault probability should be determined by measuring the change in position of the peak maximum and not the cg (which would include the effect of twin faults). This was indicated in the original theory and is shown more explicitly here. (Author)
