Abstract
We have investigated the behaviour of antiphase boundaries as a function of temperature in A3B binary ordered alloys using transmission electron microscopy. The study shows a typical wetting phenomenon at the order-disorder transition. At low temperature, the domain walls are perfectly thin and micro-faceted. Complete interfacial wetting by the disordered phase, characterized by a logarithmical divergence of the width of the walls, is shown to occur when approaching the order-disorder transition from below.
