Structural Classes

A study of the structure and strain-hardening ability relationship was carried out in this work for wear-resistant steels of two structural classes: high-manganese austenitic steel 110G13L and metastable austenitic chromium-manganese steel 60G9KhL. It is shown that the strain-hardening ability can be estimated using a methodologically simple engineering criterion. The criterion determines the metal tendency to harden by determining the Rockwell hardness at the bottom of the indentation cup of the Brinell press indenter

The article is devoted to the analysis of known structures of impact devices used in industry in order to obtain recommendations for their adaptation or when creating new structures for wave strain hardening by surface plastic deformation. The analysis was carried out on the used drive and on the main parameters of impact devices: impact energy, impact frequency, relative metal consumption and efficiency. The options are the best combinations of parameters for electric, pneumatic and hydraulic drives. Recommendations are given on the use of such devices, with appropriate adaptation, as pulse generators for wave strain hardening.

Theoretical Results

The results of an experimental check of the obtained theoretical formulae allowing us to determine the most important parameters of extrusion cartridges with a counterpunch for different hollow radiuses and bottom-most part thicknesses are presented. Characteristics of used tools, geometric parameters of extrusion experiments, strength characteristics of deformed materials and lubricants are described in detail. Both strain-hardening material and strain-unhardening material were studied. Methodology of the theoretical calculations is demonstrated in detail. High accuracy of the obtained design formulae was confirmed.
