Electron Microscopic Study of Domain Structure in Iron-Aluminum Alloys

Kensuke Oki, Hiromichi Sagane and Tetsuo Eguchi

(Received November 15, 1973)

The change in the micro-domain structure of Fe-Al alloys during the isothermal annealing has been investigated by means of transmission electron microscopy. The domain structure shows very complicated features in each transition, but the results of the observation are consistent with those of our previous work using X-ray diffraction. In the transitions B2→α+B2 and α+B2→α+DO₃ the decomposition of the ordered phase into a mixture of the ordered and disordered phases takes place. The transition α+DO₃→DO₃ is dominated by the nucleation of DO₃ domains in the disordered phase. In the reverse process, from DO₃ to α+DO₃, the disordered phase precipitates in two steps from the DO₃ phase.
