Distribution of deformations and parameters of stress-strain state in steel Kh18N10T

Abstract

Parameters of the laws of distribution of fields of micro- and submicrodeformations in steel Kh18N10T are determined under uniaxial tension of specimens. The components of the plastic strain tensor and their statistics are determined for grain arrays and in the plane of four individual grains. The intensities of the major micro-and submicrodeformations are computed. The correlation relations between the deformations of individual volumes of metal inside grains are estimated. The parameters of the strain-stress states of structural components (grains) of a polycrystal are determined. Qualitative analysis of the microstructural features of deformation of the steel studied is performed. © 2013 Springer Science+Business Media New York
