New data were obtained on the effect of small additions of magnesia nanoparticles on the mechanical properties of aluminum. Composite specimens were produced by cold pressing of aluminum powders with or without copper added with subsequent sintering in a forevacuum. As a result, a significant increase was detected in the strength properties of materials modified by magnesia nanoparticles, namely, in tensile, compressive, flexural, and offset yield strengths.

通过添加氧化镁纳米颗粒提高铝粉材料的强度性能

获得了少量添加氧化镁纳米颗粒对铝机械性能影响的新数据。复合试样是通过冷压铝粉，添加或不添加铜，然后在前级真空中烧结制成的。结果，检测到由氧化镁纳米粒子改性的材料的强度特性显着增加，即拉伸、压缩、弯曲和偏移屈服强度。
