چکیده انگلیسی


• ε-Phase stabilization in Fe-Mn alloys by high-pressure torsion was investigated.
• Nearly 100 vol% ε-phase was obtained in Fe-30%Mn alloy after high-pressure torsion.
• ε-Phase stabilized in the Fe-20%Mn-0.8%C alloy with high γ-phase stability.
• Stabilized ε-phase reverse transformed at a temperature between 473 and 623 K.

Stabilization behaviors of high-pressure ε-phase by high-pressure torsion process in the Fe-Mn alloys having different stacking fault energies (i.e., γ-phase stabilities) were investigated. Stabilization of high-pressure ε-phase at ambient condition after the HPT process was observed regardless of sample composition. It was found that the HPT process could stabilize ε-phase in the composition with high γ-phase stability. Volume fraction of stabilized ε-phase increased with increasing applied hydrostatic pressure. The formed ε-phase reverse transformed to γ-phase at the temperature between 473 and 623 K.
