The possibilities of strain hardening and the formation of a substructure of 17Х14Г19АФ steel  with stable austenite during bulk mechanical deformation of samples under cavitation wear are investigated. It was found that for both types of deformation in Fe-Cr-Mn-N steel with stable austenite with previous dispersion strengthening, strain hardening occurs by dislocation by the Orowan mechanism.
