Abstract
High-speed torsion tests at temperature and deformation parameters close to friction stir welding are performed on a Gleeble-3800 installation. The tests are carried out at elevated temperatures at the same strain and different strain rates. EBSD is used to study the influence of the temperature and deformation parameters of high-speed torsion on microstructure formation in some alloys. A quantitative microstructural analysis is conducted to determine the grain sizes in various deformation zones. The dependence of the grain size of the temperature and deformation parameters of high-speed torsion is revealed. The temperature and deformation parameters ensuring the formation of a fine-grained structure are determined.
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.
