Prediction of the Mechanical Behavior of Smooth Metallic Specimens Hardened by Combined Electromechanical and Ultrasonic Treatment during Soft-Cycle Axial and Bending Loading

A semi-analytical model is proposed to describe the deformation of metallic specimens, which are surface hardened by combined electromechanical and ultrasonic treatment, during soft-cycle axial and bending loading at a given stress ratio. An algorithm is described for reconstructing the stress–strain and fatigue strength curves of a high-strength surface layer. Examples of reconstructing such curves for grade 45 steel are provided; they are based on the results of a limited number of experiments on specimens with and without a continuous hardened surface layer.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
