| 摘 要： | 利用纳米Sn粉高的表面活性,通过微米Mg粉与纳米Sn粉的机械合金化高效合成了含原位纳米Mg2Sn相的复合粉末,将所得复合粉末热压烧结,获得高性能纳米Mg2Sn增强镁基复合材料。对比研究了不同机械合金化时间对镁基复合材料组织、性能的影响,结果表明：随着机械合金化时间的延长,由纳米Mg2Sn相组成的团簇尺寸不断减小,分布更加均匀,烧结态Mg2Sn/Mg复合材料的各项力学性能也得到不断提高。

| Abstract: | Due to high surface activity of nano Sn powder, the mixture powders containing in-situ nano Mg2Sn phase were synthesized efficiently by milling micro Mg powders and nano Sn powders. High-performance Mg2Sn/Mg composites were then prepared by hot-press sintering from the milled mixture powders. Effect of milling time on microstructure and properties of Mg2Sn/Mg composites were investigated comparatively. The results show that, with the increase of milling time, the size of Mg2Sn clusters consisting of Mg2Sn nanophase decreases continuously, and Mg2Sn clusters are distributed uniformly in the matrix. Moreover, the mechanical properties of sintered Mg2Sn/Mg composites are also gradually improved. |
