Theoretical analysis of distortion tensors in the formation of 90°<110> reorientation nanobands in the process of plastic deformation of nickel on Bridgman anvils
Based on the results of electron microscopic studies, a theoretical study of the distortion tensors of the strain localization nanobands with 90° <110> reorientation of the crystal lattice was conducted. The analysis was carried out in the direct plus reverse model of FCC®BCC®FCC martensitic transformations in the approximation of the linear theory of small strains. Using the atomic model of martensitic transformations based on a system of cooperative thermal fluctuations of planes in the BCC lattice, the distortion tensors of the contraction and shear deformation modes, as well as their contribution to the total distortion of the reversible martensitic transformation were estimated.
