Abstract

Abstract Four kinds of Ti–Al intermetallic compounds were made from powder metallurgical processing using mechanical alloying or plasma rotating electrode processing. One consisted of α2-Ti3Al single phase, and the others consisted of α2-Ti3Al and γ-TiAl duplex phases. These intermetallic compounds were irradiated at 673 K to the fluence of 5.16 × 1025 n/m2 (E > 1 MeV) in the high flux isotope reactor. After irradiation, transmission electron microscopy was carried out. Cavities were observed in both the α2-Ti3Al- and γ-TiAl-phases. The nucleation behavior of cavities in the α2-Ti3Al- and γ-TiAl-phases was influenced by chemical composition and fabrication processes.
