Abstract

ω-phase in α₂+γ lamellar structure of Ti-45Al-10Nb alloy (atomic fraction, %) was investigated by high resolution electron microscopy (HREM). The orientation relationship between ω phase and α₂+γ lamella was identified as [0001]_ω // 〈112̄0〉α₂ // 〈11̄0〉_γ, {112̄0}_ω // (0002)α₂ // {111}_γ. The ω phase with B8₂ structure further evolved to ω* phase with D8₈ structure in α₂ lamella. It is possible that α₂ → ω direct transition occurred in lamellar structure.
