Influence of Heat and Vibration Treatment on the Cold Resistance and Structure of ER70-S6 Steel Fabricated by 3D Printing Using Electric Arc Cladding
Abstract—The influence of heat and vibration treatment on the structure and mechanical properties of experimental specimens prepared from an ER70-S6 welding wire by additive electric arc growth is considered. Based on the results of impact strength tests, the cold resistance of the experimental specimens is estimated. Electron microscopy is used to analyze the microstructure of the material and to calculate the grain size. Heat treatment and vibration treatment are shown to significantly increase the cold resistance of the materials produced by electric arc cladding. Replacement of heat treatment operations is possible by introducing the function of vibration treatment of a weld pool into hybrid machining centers.
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.
