本文研究了功能梯度AlB2增强Al-4%Mg复合材料的制备。在1400℃下向液态Al-Mg中加入氧化硼，获得了原位高深宽比片状Alb2增强相。观察到，Alb2有两个明显的无光滑级配区域：一个是富Alb2，另一个是贫Alb2。结果表明，外区Alb2含量最高为10%左右，内区Alb2含量最低为0.02%。此外，研究结果还表明，随着外区增强相的增加，复合材料的硬度提高了20%。
In this study, production of functionally graded AlB 2 reinforced Al-4%Mg composite has been investigated. In-situ high-aspect-ratio flake AlB 2 reinforcement was obtained by the addition of boron oxide to the liquid Al-Mg at 1400 °C. It has been observed that there were two distinct regions without a smooth grading: one is rich of and the other is poor of AlB 2 . The results showed that the highest AlB 2 content has been found to be around 10% in external zones, whereas the lowest AlB 2 content has been observed to be 0.02% in the internal zones. Additionally, results showed that, depending on the increase in the reinforcement phase in external zones, up to 20 % increase in the hardness of the composite has been achieved.
