The role of grain-boundary disorder in the generation and growth of antiphase domains during recrystallization of cold-rolled Cu3Au

An experimental study by transmission electron microscopy was made of the morphology of the antiphase domains formed when heavily rolled Cu3Au is annealed at a temperature slightly below the critical temperature for ordering, Tc. Domains are formed at the advancing grain boundary with extremely small size and they grow as recrystallization proceeds. From an early stage, domain walls show a preference for {100} orientations.
