中文摘要：

碳 nanotubes (CNT ) 增强了 Mg 矩阵 composites 被一篇小说制作融化处理。处理的小说由二堂功课组成了：CNT 分散前并且超声融化处理。机械球工厂被采用到预先分散锌(Zn ) 薄片上的 CNT。严肃的 CNT 纠纷很好被驱散在 Zn 薄片上挑选 CNT 或微小的簇。超声融化在 Mg 处理进一步驱散的 CNT 融化，特别微小的 CNT 簇。因此， CNT 的一致分散在当演员组 composites 被完成。热挤出进一步改进了 CNT 的分发。CNT 增加了矩阵合金的力量和延伸。尤其是，矩阵合金的延伸被 40% 提高。谷物精炼和 CNT 的拉外面为 composites 导致了韧性的明显的改进。

英文摘要：

Carbon nanotubes（CNTs） reinforced Mg matrix composites were fabricated by a novel melt processing.The novel processing consisted of two courses：CNTs pre-dispersion and ultrasonic melt processing.Mechanical ball-milling was employed to pre-disperse CNTs on Zinc（Zn） flakes.Serious CNT entanglements were well dispersed to single CNT or tiny clusters on Zn flakes.The ultrasonic melt processing further dispersed CNTs in the Mg melt,especially tiny CNT clusters.Thus,a uniform dispersion of CNTs was achieved in the as-cast composites.Hot extrusion further improved the distribution of CNTs.CNTs increased both the strength and elongation of the matrix alloy.Notably,the elongation of the matrix alloy was enhanced by 40%.Grain refinement and the pulling-out of CNTs resulted in the evident improvement of ductility for the composites.
