Structure of the ε martensite plate intersections in Fe-Mn-Si-Al TRIP/TWIP steels

摘要

Various deformation microstructures at the s - s intersections have been reported for SMA depending on the investigators: the a' martensite, the secondary s phase with distinct crystallographic orientations from the initial s plates, γ twin and s twins. However, there is no detailed analysis of the structure of the intersection in the TRIP/TWIP steels. In this study, the e-s intersection in an Fe-30Mn-4Si-2Al TRIP/TWIP steel was investigated in detail.
