| 英文摘要 | Low-cycle fatigue behaviors of CrCoNi medium entropy alloy with different grain sizes were investigated. It is found that grain refinement improved deformation homogeneity to delay fatigue crack initiation by dispersing slip bands and fatigue damage. Yet, the increase in grain size promoted deformation twinning to retard fatigue crack growth by dissipating plastic work. With enough plastic deformation accumulated, extensive dislocation slip and deformation twinning significantly refined the grains localized near fatigue cracks. The grain refinement could trade off the cyclic softening and help to retard fatigue crack growth. These findings indicate that refined grains with certain twinning ability would extend the fatigue life of CrCoNi alloy the most and suppress cyclic softening at the same time. |
