Abstract: To explore the mechanism of damage-induced magnetization for
paramagnetic austenitic stainless steel, the differences of damage-induced
magnetizations between an austenitic stainless steel and a carbon steel are
experimentally studied. Various plastic strains are introduced into the
test-pieces of the austenitic stainless steel of 304 type and S185 carbon steel
material. The residual plastic strains and the damage-induced magnetic fields
nearby the test-pieces, the volume fraction of the damage-induced ferromagnetic
martensitic phase in austenitic stainless steel test-pieces are measured. The
relationships between the residual plastic strain and the damage-induced
magnetic field of two materials are investigated and their differences are
compared. In addition, by establishing the relationships of the damage-induced
magnetic field with the damage-induced martensitic phase, the effect of the
phase transformation on the damage-induced magnetization of austenitic
stainless steel is analyzed.
