Abstract
Electron-irradiation-induced phase transition in Cr2M (M = Ti and Al) intermetallic compounds was investigated by high-voltage electron microscopy (HVEM). Under MeV electron irradiation, the Cr2Ti intermetallic compound transformed into an amorphous phase, which was followed by the precipitation of a b.c.c. solid solution, indicating the occurrence of a crystalline-to-amorphous-to-crystalline (C–A–C) transition. In contrast, in the Cr2Al intermetallic compound, the formation of the b.c.c. phase occurred directly without an amorphous phase formation through electron-irradiation-induced chemical disordering. These transitions were discussed on the basis of Cr–M binary phase diagrams and a Gibbs free energy model.
