Evidence supporting reversible martensitic transformation under cyclic loading on Fe-Mn-Si-Al alloys using neutron diffraction

Sawaguchi, Takahiro*; Tomota, Yo*; Yoshinaka, Fumiyoshi*; Harjo, S.

Fe-Mn-Si-based alloys, show superior resistance to plastic fatigue compared to the conventional steels, which is ascribed to the reversible back-and-forth movement of Shockley partial dislocations associated with a reversible martensitic transformation between the face-centered cubic -austenite and hexagonal close-packed -martensite. The purpose of this study was to gather evidence of the reversible martensitic transformation using in situ neutron diffraction under cyclic loading. Three Fe-30Mn-Si-Al alloys with different Gibbs free energy differences at 298 K were studied to unravel the effect of phase stability on the degree of reversibility.
