Abstract

High Nb containing TiAl based alloy has more excellent mechanical properties than traditional TiAl based alloy, but ω phase which is a hard and brittle phase in as-cast, as-worked and thermal exposed high Nb containing TiAl based alloy in the range of service temperature is bad for the improvement of mechanical properties and limits the further application of high Nb containing TiAl based alloy. In the present paper, the progress in research on ω phase in high Nb containing TiAl based alloy is summarized. Mechanism of ω phase formation, microstructure morphology, the effect on mechanical properties and elimination of ω phase in high Nb containing based alloy are discussed.
