| 英文摘要 | The microstructural evolution and hardness changes of Alloy 718 under low dose (<= 0.09 dpa) proton irradiation were investigated. Low dose irradiation induced the formation of defect clusters and disordering of the gamma '' phase, while no voids or radiation-induced segregation were observed. The density of defect clusters increased with increasing irradiation dose, but their size did not change significantly. The irradiation damage behavior varied among different gamma '' variants, with those having their [001] direction parallel to the proton beam being the most resistant to disordering. The hardness of the irradiated material was simultaneously affected by the hardening due to irradiation defects and the softening caused by the disordering of the gamma '' phase. The competition between these two factors led to a decrease in hardness at 0.02 dpa and 0.04 dpa compared to the unirradiated material, while at 0.09 dpa, the hardness increased above that of the unirradiated material. |
