摘要：

Plastic deformation mechanisms of low-density Fe-Mn-Al-C austenitic steels are discussed based on the dislocation substructure evolution during tension at ambient temperature. Even with the high stacking fault energy, due mainly to the high Al content, substructures associated with planar glide, such as Taylor lattice, Taylor lattice domain boundaries and microbands, were progressively developed with strain. Along with the origin and the nature of such substructures, the contribution of these substructures to the strain hardenability of these steels is discussed. (C) 2012 Acta Materialia Inc.
