| 英文摘要 | In-situ electron irradiation and aging are applied to introduce high-density precipitates in an Mg-10Gd-3Y-1Zn-0.5Zr (GWZ1031K, wt.%) alloy to improve the hardness. The results show that the hardness of the Mg alloy after irradiation for 10 h and aging for 9 h at 250 degrees C is 1.64 GPa, which is approximately 64% higher than that of the samples before being treated. It is mainly attributed to gamma ' precipitates on the basal plane after irradiation and the high-density nanoscale beta' precipitates on the prismatic plane after aging, which should be closely related to the irradiation-induced homogenous clusters. The latter plays a key role in precipitation hardening. This result paves a way to improve the mechanical properties of metallic materials by tailoring the precipitation through irradiation and aging. (c) 2022 Chongqing University.
