摘要

通过对纳米SiC颗粒的预处理

使用搅熔复合铸造工艺

制备了纳米SiC颗粒增强AM60铸造镁合金材料。研究了纳米SiC颗粒对镁合金的显微组织、力学性能和硬度等的影响。结果表明

在镁合金中添加纳米SiC颗粒能够细化其组织

提高材料的综合力学性能。当纳米SiC颗粒加入量（体积分数）为1.0%时

纳米颗粒增强AM60镁合金的抗拉强度、伸长率和硬度（HB）分别达到240MPa、16.0%和53.9

较相同工艺下未加纳米颗粒的AM60分别提高了12.1%、40.3%和11.6%。同时对纳米SiC颗粒对镁合金的强化机理进行了探讨。

Abstract

Pretreated nano-SiC particle reinforced AM60 magnesium alloy was fabricated by stirring-smelting casting. Effects of nano-SiC particle on the microstructure

mechanical properties and hardness of the Mg alloy were researched. The results show that nano-SiC particle can refine the microstructure and improve the comprehensive mechanical properties of the AM60 magnesium alloy. The tensile strength

elongation and hardness of the nano-particle reinforced AM60 Mg alloy with 1%nano-SiC particle addition is 240 MPa

16% and 53.9

increased by 12.1%

40.3% and 11.6% respectively compared with that of the AM60 Mg alloy without nano-SiC particle with the same method.Meanwhile

the strengthening mechanism of nano-particle SiC on the AM60 magnesium alloy was approached.
