Effect of Elastic Deformation by Compression, Tension,and Torsion on the Critical Magnetic Field Distribution in a Steel 15XH4Д

摘要

Effect of deformation by compression, tension, and torsion on magnetic characteristics and critical magnetic field distribution in a high-strength economically alloyed structural steel 15XH4Д. The coercive force, residual induction, and maximum magnetic permeability vary definitely with changing stresses. This fact gives the principal possibility to use these characteristics as parameters for magnetic testing of elastic strains. Moreover, the studies of critical magnetic field distribution allow us to obtain data on the volume of the ferromagnet, which has changed its state in a given magnetic field under certain mechanical stresses.
