Evolution of contributions from components of lattice bending–torsion to the elastic component of internal stresses during the deformation of a polycrystal

Resumo

The contributions from the components of lattice bending–torsion to the elastic component of internal stresses are determined and the evolution of these components at various degrees of deformation of 1.1–13Mn–Fe austenitic steel is studied. The components of the internal stress tensor are determined using the parameters of the bending extinction contours observed in electron micrographs of deformed specimens. The results are discussed by comparing them and the defect structure of the deformed steel.
