Abstract
Thermal grown-in antiphase boundaries (APBs) of the next-nearest neigh bour (APB2) type in the Fe-28Al-5Cr (at.%) alloy were studied in the e dge-on orientation by means of high resolution electron microscopy. Th e interfaces are thin and sharp. The domain walls are rugged, small fa cets (ledges) 0.5-5 nm long situated in the (100) and (111) planes wer e observed. Two different structures of the APB2 interface with opposi te fault vectors were found. Their atomic arrangements are interpreted by contrast simulations, using two models of stacking of the Al and F e planes in the boundary. (C) 1997 Elsevier Science S.A.
