Abstract

The sequential microstructural evolution of abnormal grain growth in the aluminum alloy was traced by ex situ observation using electron-backscattered diffraction during secondary recrystallization. Near the growth front of abnormally growing grains, many three- or four-sided grains with a negative curvature, which had the same orientation as abnormally growing grains, were penetrating the surface, indicating that abnormal grain growth occurs dominantly by repeated events of triple-junction wetting. Also, abnormally growing grains were shown exclusively to have sub-boundaries.
