| 英文摘要 | CoCrFeMnNi high-entropy alloys (HEAs) with partially recrystallized (PR) structure were fabricated by cold rolling and annealing. The microstructures were characterized and the tensile properties were tested at 77 K and 293 K, respectively. In contrast to the early necking at 293 K, an ultrahigh yield strength of 1692 MPa and a considerable uniform elongation of 10.3% were obtained at 77 K. The notable uniform elongation at 77 K can be attributed to the enhanced strain-hardening capability via introducing multiple deformation mechanisms in the recrystallized grains. This work provides a strategy to design high-strength high-ductility HEM for applications at cryogenic environments. |
