Abstract
The results of the measurements of the magnetic properties of plastically tensile-deformed samples of grade 08X15H5д2T maraging steel are represented. Preliminary the samples were subjected to annealing, quenching, and ageing with a variation in temperature and holding time for obtaining of the various initial contents of retained austenite. It was found that the testing of the content of retained austenite in the deformed state is possible by saturation induction Bs. The use of the structural-sensitive parameter N′ (an analogue of the internal demagnetization factors) allows one to determine the content of retained austenite in the undeformed state and in the prerupture state and the qualitative separation of plastically deformed and undeformed products of grade BHC-2УШ steel.
