Influence of severe plastic deformation (SPD) under high pressure on martensitic phase transformations and hardening of Fe-Mn alloys has been studied. The named alloys with wide concentration content of manganese (from 0 to 55 wt.%), having in initial state bcc, hcp and fcc (stable and metastable austenite) phases after thermoplastic treatment and quenching from 1370 K in water were as the objects under investigation. SPD under high and ultra-high pressure was performed by the means of hydroextrusion techniques, torsional shear under pressure and usage of diamond anvil cell (DAC). The ranges of pressure varies from 0 to 60 GPa and the deformation degree does not exceed 10 units of true deformation, accordingly.
