Investigated in this work is the plastic deformation of representative mesovolumes of the steel 65Cr13 samples. They were surface-hardened by ion nitriding. An evolution of inner structure and stress-strain state in the mesovolumes with different thickness of surface-hardened layer was analyzed under tension and compression. A site of the working part of a cross-section of the sample was examined in the area of neck formation. To simulate the two-dimensional behavior of the deformed steel samples, two formulations are given. They include the strain hardening effects and crack formation. The results are presented and discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
