Features of course martensite transformation in steel at hardening in the constant magnetic field

Using the method of electroresistance obtains data about course martensite transforma-tions in steel under action of the magnetic field, formations specifying an opportunity stress-assisted martensite in temperature interval S-F in which superplasticity is shown. This opportunity is caused by magnetic heterogeneity austenite, presence in a paramagnetic matrix nanostrustural ensemble ferromagnetic ordering clusters which per-ceiving energy of an external magnetic field through magnetostrictive pressure, change fields of elastic forces in microvolumes of a nuclear lattice of a matrix, that causes to decrease in energy of formation germinal center of the critical size.
