摘　　要：对国内外在TiAl基合金的超塑性研究中所提出的各种变形机理和调节机制进行了综述,并介绍和分析了该合金在超塑性变形中所呈现的各种应力-应变关系。The mechanisms of superplastic deformation and their accommodation for TiAl based alloys are reviewed in different experimental conditions such as composition, microstructure, grain size, process parameters etc. in the present paper. The true stress - true strain relationships during superplastically deforming are also introduced and analyzed in relative detail.
