摘要：

The carried out transmission electron microscopic (TEM) analysis of steels 316L and TWIP, has shown that important mechanisms of plastic deformation are mechanical twinning, shear band formation and deformation martensitic transformations. Mechanical twinning is a characteristic feature of a plastic deformation at epsilon approximate to(20-50)% deformation degrees. At epsilon = (20-70)% the basic contribution in plastic deformation of a material brings shear band formation. The contribution deformation martensitic transformations into plastic deformation is defined by level of phase instability of steels.
