在C/Mg 复合材料液态成形工艺中,于基体 Mg 中加入微量元素 Be,可改善合金的抗氧化性,同时有利于纤维在基体中的均匀分布。研究发现是由于 Be 在 Mg 液表面富集造成,对其机理进行了探讨。
In the liquid forming process of C / Mg composites, addition of microelement Be to the matrix Mg can improve the oxidation resistance of the alloy and at the same time facilitate the uniform distribution of the fibers in the matrix. The study found that due to Be enrichment on the Mg liquid surface, its mechanism was discussed.
