摘要：

The nature of the surface phase transitions associated with the bulk compositional order-disorder transition in Cu3Au crystal is discussed from the experimental standpoint. The available facts about the order of the surface transition, the accompanying change of surface-layer compositions, and the ordering kinetics are assembled. It is shown that seemingly disparate properties of the (100) and (110) surfaces can be correlated with each other, and with corresponding properties of the bulk crystal, by considering the surface structures arising from type I domain walls. © 1990.
