| 英文摘要 | The low-cycle fatigue (LCF) life of conventional materials is largely dependent on their ductility, i.e., the better the ductility, the longer the LCF life. In this work, 316L stainless steel (SS) was subjected to dynamic plastic deformation , subsequent annealing to obtain single-phase heterostructured samples consisting of recrystal-lized grains and remaining nanostructures. The tensile ductility of the heterostructured 316L SS increases monotonically with increasing volume fraction of recrystallized grains, while the strain-controlled LCF life first decreases and then increases, partially deviating from the monotonically increasing LCF-ductility relation. The reason is that the recrystallized grains with a low volume fraction (<= 25 vol.%) in heterostructured 316L SS sustain high cumulative plastic strain due to plastic strain partitioning, leading to cracking in the recrystallized grains at the early stages of LCF and thus reducing the LCF life. |
