Controlled Formation of the Designed Mechanical Properties of Machine Parts by Deformation Hardening in the Conditions of Complex Local Loading of the Deformation Zone

Abstract

The process of complex local loading of the deformation zone is considered using the example of processing a sleeve made of a bronze alloy, the mechanical properties of the cast alloy under study were determined, and the parameters of the microhardness distribution over the cross section of the processed workpiece were investigated. Plots of the distribution of various microhardness parameters over the cross section are plotted depending on the number of processing cycles. A mathematical model of the process under consideration and its comparison with experimental data is shown. The description of the technique in the form of an algorithm of actions for the appointment of technological parameters. An example is presented in the form of a finished nomogram for the assignment of specific processing parameters to obtain a given hardening depth and value.
