Abstract

High manganese austenitic steels with various mean grain sizes (1.8, 7.2, 49.6 μm) were tensile tested and their twinning behaviors were studied. The fine-grained steel (d = 1.8 μm) showed high strength with adequate ductility. Deformation twinning was strongly inhibited by grain refinement. These observations suggest that the reason for the large ductility lies on not only the twinning but also in the suppressed dynamic recovery due to low stacking fault energy.
