报告摘要:
Breaking the trade-off between strength and ductility/strain hardening has long been a great challenge for high-strength metallic materials. In this talk, I aim at reviewing a critical assessment of the state of the art of a few gradient nanostructured materials, such as dual-gradient nanotwinned (GNT) Cu as well as gradient cell-structured alloys, covering topics ranging from fabrication, unprecedented mechanical properties and the fundamental deformation mechanisms. Our findings provide a promising paradigm for tailoring properties with gradient structures at nanoscale and advance our fundamental understanding of the intrinsic deformation mechanism of gradient nanostructured materials.
