Abstract

The alloy CuAu becomes ordered below a critical temperature of about 420° C, so that the (002) planes of the f. c. c. structure (CuAu I) contain alternately all copper and all gold atoms. It was originally deduced from X-ray diffraction evidence (1) that regularly spaced anti-phase domain boundaries occur under certain conditions of annealing. At an anti-phase boundary, which is perpendicular to [100], an (002) plane of copper atoms on one side of the boundary is coplanar with a plane of gold atoms on the other side of the boundary. The boundaries occur every 20 Å along [100]. This is known as the CuAu II structure.
