Outline of Final Research Achievements

Abnormal grain growth phenomenon induced by cyclic heat treatment through α→α+β→β phase transformations was investigated in Cu-Al-Mn and Fe-Mn-Al-Ni alloys. It was found that the subgrain structure forms associated with precipitation of the second phase and that it exists after solution treatment. Annealing at higher temperatures resulted in abnormal grain growth, and the subgrain free zone was observed after migration of the high-angle boundary. The abnormal grain growth can be explained by considering the sub-boundary energy as a driving pressure.
