英文摘要	The macro-deformation of crystal attributes the micro-slip in crystal of gamma-TiAl alloy. So it is important to reveal the relation between macro-deformation and micro-slip of dislocation. In order to illustrate this relationship, the geometry relation between macro-deformation and dislocation density/external shear stress was established, which was based on the uniaxial tension model. According to the analysis about the relationship, the expression between strain rate of macro-deformation and dislocation density/external shear stress has been obtained. Besides, the curve between strain rate of macro-deformation and external shear stress has been got.
