Peculiarities of the Magnetic Behavior of Pipe Steels with Different Initial Stress–Strain States Under Elastic Deformation
The effect of the value of preliminary plastic deformation viewed as an initial stress–strain state on the magnetic behavior of X70 pipe steels under elastic tension and compression is studied. Magnetic characteristics were measured both in a closed magnetic circuit and with the use of attached transducers along the direction of applied loading. The plastic deformation history affects the magnetic behavior of the material during subsequent elastic deformation, as plastic strain induces various residual stresses, and this necessitates taking into account the initial stress–strain state of products when developing magnetic techniques for the determination of their stress–strain parameters in operation.
