Structural, Physical and Mechanical Aspects of the Effect of Structural-Wave Magnetic Resonance Treatment on Low-Carbon Martensitic Steels

The influence of an alternating magnetic field in the austenitic temperature range during structural-wave magnetic resonance treatment (SWMRT)combined with thermocycling treatment (TCT) on the structure, physical and mechanical properties of low-carbon martensitic steel 08Kh2G2NMFB is investigated. The changes in the microstructure after the treatment are determined by metallographic, electron-microscopy and x-ray diffraction analyses. The elasticity parameters after the SWMRT are studied. Steady values of the temperature frequency coefficient are obtained for steel 08Kh2G2NMFB after the SWMRT + TCT in the range of (113 – 116) × 10 ^{– 6} K^{– 1}.
