摘要：
Nanotwins with high density have been introduced by severe plastic deformation to improve the mechanical properties of single-phase steels. In this article, we revealed a pathway to generate intensive nanotwins in a dual-phase medium Mn steel. These nanotwins are developed by martensitic transformation during the quenching process and twinning-induced plasticity (TWIP) effect during subsequent uni-axial tension. The complex nanotwins with very high twin density will be promising for enhancing the mechanical performance of steels.
