Abstract
A systematic study of the influence of various types of mechanical action on magnetic properties and energy losses during remagnetization in electrical steels was carried out. Using a specially designed and manufactured experimental setup, samples of various types of electrical steels were studied at magnetization reversal frequencies of up to 5 kHz and magnetic induction amplitudes of up to 1.9 T. It was found that the deterioration of magnetic properties occurs to a lesser extent during the manufacture of samples by waterjet cutting compared to laser processing. It was shown that as a result of heat treatment at 900°C in vacuum, the magnetic properties are restored to their original values. The experimental results of measuring energy losses during frequency magnetization reversal were compared with theoretical models.
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.
