The experimental results of the evolution of hysteresis magnetic characteristics, Barkhausen magnetic noise parameters and electromagnetic parameters of metastable austenitic AISI 304 steel (analog of 12Kh18N10 steel) under biaxial symmetric tension have been presented. Studying was carried out on the original biaxial testing machine, allowed to determine the physical properties of materials during elastic-plastic deformation independently along two axes.
K.D. Malygina (Wed,) studied this question.
