摘要：
The elastic constants Of alpha(2) phase of a two-phase TiAl-based intermetallic alloy were determined experimentally by X-ray diffraction method. From these results, the residual stresses and the mechanical state Of alpha(2) phase in the alloy, induced by a uniaxial tensile loading, were characterized by X-ray diffraction. It was found that the X-ray elastic constants of alpha(2) phase differ from those of gamma phase and the macroscopic ones, the mechanical state of alpha(2) phase shows a great difference compared with that of gamma phase, and the reasons were discussed.
