摘要：

The coherent instability temperatures for continuous ordering have been determined for various binary alloys from absolute intensities of X-ray diffuse scattering. The measured Tinstability are 358.2, 211.4 and 627.6°C for alloys of Cu3Au, Cu81.5Au18.5 and CoPt3 respectively. A comparison is made of these values to mean field theories and to recent calculations of the Cu-Au phase diagram by means of the cluster-variation method, including nearest-neighbor tetrahedra. © 1979.
