Strategy for managing both high strength and large ductility in structural materials–sequential nucleation of different deformation modes based on a concept of plaston

Based on recent findings in ultrafine grained metals, we proposed a strategy for overcoming the strength-ductility trade-off in structural metallic materials. Sequential nucleation of different deformation modes, such as unusual slip systems, deformation twinning, martensitic transformation, etc., would regenerate strain-hardening ability of the material, leading to high strength and large tensile ductility. For discussing the activation of...
