X‐ray study of stacking faults in a double hexagonal close‐packed AuCdIn alloy

摘要

A study of the x‐ray powder pattern resulting from a cold‐worked hexagonal close‐packed AuCdIn alloy containing 17.5 at.% Cd and 5.0 at.% In has been made. Quantitative analysis of observed anomalous peak broadening, peak shifts, and peak asymmetry in the powder pattern shows evidence for only three of the nine faults, which have earlier been postulated for this structure, namely intrinsic‐ch, intrinsic‐h, and intrinsic‐2h with respective fault probabilities of αch=0.045, αh=0.036, and α2h=0.002.
