| 英文摘要 | The fracture behavior was investigated of a bulk nanostructured 316L austenitic stainless steel with embedded nanotwin bundles incorporated by dynamic plastic deformation. The nanotwin bundles were demonstrated to be critical to strengthen and toughen the as-deformed samples with mixed microstructures of nano-grains and nano-twins. With increment in strength, the fracture toughness decreases due to the generation of increasingly more nano-grains. Additional controlled thermal annealing that makes the nano-grains recover or recrystallize leads to reduced strengths but more remarkably improved fracture toughness. The enhanced strength fracture toughness synergy can be attributed to the nano twin bundles that constrict the damage development in the matrix of either nano-grains or recrystallized grains, and that resist crack propagation via acting as ductile crack bridging ligaments.
