摘要：

In situ transmission electron microscopy experiments coupled with resistivity measurements have been performed on Copta. The antiphase boundaries separating different L12 (Cu3Au-type) ordered domains are shown to be progressively wetted by the disordered phase when approaching the critical order-disorder transition from below. This is in excellent qualitative agreement with previous cluster variation method calculations by Kikuchi and Cahn. © 1990 IOP Publishing Ltd.
