The e-beam irradiation effect is investigated on mechanically alloyed Y₂O₃-Al6061 composites with different reinforcement ratios (0.25, 2, 6 % wt.). Uniform dispersion of reinforcement elements in the Al matrix is achieved according to SEM and EDS analysis in conjunction with the formation of a highly dense structure. Improvement in hardness value is observed by increasing both the amount of reinforcement species and irradiation dose, concomitantly. The samples are irradiated with 6 MeV and 18 MeV electrons, along with 2, 4, and 6 kGy radiation amounts. 6 MeV radiation has minimal effect on alloys and samples preserve structural integrity. However, electron irradiation with 18 MeV energy shows a distinguished influence on Y₂O₃-reinforced alloys by initiating defects and defect clusters in samples and eventually leading to expansion in unit cell volume. Finally, it is important to state that the 6 % Y₂O₃-Al6061 materials system is more suitable for applications where e-beam irradiation is used.

研究了不同增强比（0.25、2、6% wt.）的机械合金化 Y ₂ O ₃ -Al6061 复合材料的电子束辐照效应。根据 SEM和 EDS 分析，结合高致密结构的形成，实现了增强元素在 Al 基体中的均匀分散。通过同时增加增强物质的量和辐照剂量观察到硬度值的改善。使用 6 MeV 和 18 MeV 电子以及 2、4 和 6 kGy 辐射量照射样品。6 MeV 辐射对合金的影响最小，样品保持结构完整性。然而，18 MeV 能量的电子辐射通过引发样品中的缺陷和缺陷簇并最终导致晶胞体积膨胀，对 Y ₂ O _{3增强合金显示出显着的影响。}最后，需要指出的是，6% Y ₂ O ₃ -Al6061 材料系统更适合使用电子束辐照的应用。
