摘要	A stress-induced gamma --> alpha(2) transformation phenomenon in a hot-deformed Ti-45Al-10Nb alloy was investigated by high-resolution transmission electron microscopy (HREM). This deformation-induced gamma --> alpha(2) phase transformation is an interface related process. The interfacial superdislocations emitted from the deviating semi-coherent alpha(2)/gamma interface react with each other or with the moving dislocations in the gamma-phase resulting in the formation of the stress-induced alpha(2)-phase. Meanwhile, the orientation of the gamma-phase, of which interface the interfacial superdislocation swept, was also changed. The structure of the dislocation ledges plays an important role in the formation of the deformation-induced alpha(2)-phase.
