Conclusions
-
1.
Austenitic stainless steels 0Kh16N8M3, 0Kh16N8V3, and 0Kh15N8M2 were strengthened by the direct and reverse martensitic transformations; the yield strength increased from 30 to 60 kg/mm2 as the result of phase strain hardening.
-
2.
Phase strain hardening of stainless steels results from water quenching (for destabilization of austenite), isothermal holding at −50 to −80°C (γ→α transformation), heating at 700–775°C (α→γ transformation), and thermal stabilization of austenite at 300–450°C.
