A Correlation between the Magnetic Behaviour and Damage of Metal Materials under Plastic Deformations
The effect of plastic tensile deformation on changes in density and magnetic behaviour has been studied on low-carbon steel specimens under hydrostatic pressure of 0.1 to 500 MPa in a test chamber. It has been shown that the parameters of minor magnetic hysteresis loops can be used to estimate the amount of plastic strain and the strain-related structural damage of metal.
