Variations in the Structure and Magnetic Parameters of Martensitic Steel Induced by Plastic Deformation

The effect of plastic deformation on the structure, phase composition, and magnetic parameters of maraging steel 08Kh15N5D2T was studied. The hysteresis, electromagnetic, and magnetostrictive characteristics were measured both in a closed magnetic circuit using the Remagraph C-500 hysteresis graph and by means of attached magnetic transducers. The regions of plastic deformation are experimentally determined in which the behavior of the magnetic parameters and their relationship vary with changes in structure and phase composition. Informative parameters are proposed that can be used to control variations in the structure and phase composition of the studied steel.
