Hardening Treatment by Plastic Deformation under Conditions of the Integrated Local Loading of a Deformation Zone

摘要

The paper considers the method of hardening treatment by plastic deformation under conditions of the integrated local loading of a deformation zone. The main positions of preparing and carrying out experimental research are adduced, as well as their results are provided. The authors discover the character of hardening process technological parameters influence on producing part mechanical parameters. We establish that the number of processing cycles has more influence on maximum hardening degree, whereas the instrument axial step exerts more influence on maximum depth of hardened zone. The paper presents the mathematical model of the considered process, which proved its adequacy in comparison with the results of experimental studies. It also indicates the directions for further research.
