Abstract: Some ambiguous ackowledgements about unit cells of γ phase and α_2 phase of TiAl alloy are discussed in this paper correct unit cell parameters of γ and α_2 -phase are put forward. Meanwhile, lattice distortions of rapid-solidified TiAl2Cr2Nb alloy powders and thin films are determined by XRD method.

Key words: TiAl2Cr2Nb alloy, lattice distortion
