摘要

采用半固态搅拌法制备了SiCp/AZ61镁基复合材料。利用正交试验法研究了SiC颗粒加入量、搅拌温度、搅拌时间等关键工艺参数对SiCp/AZ61镁基复合材料力学性能的影响。结果表明

SiC颗粒加入量对复合材料的力学性能有着显著的影响

其次是搅拌时间和搅拌温度。在试验条件下

SiCp/AZ61镁基复合材料的半固态搅拌工艺方案可优化为:SiC颗粒加入量为6%

搅拌温度为595℃

搅拌时间为5 min。断口分析显示

增强颗粒加入量为6%的SiCp镁基复合材料室温断口形貌呈脆性断裂特征。

Abstract

Effects of SiC addition

stirring temperature and time on mechanical properties of SiCp/AZ61 magnesium matrix composites prepared by semi-solid stirring method have been examined by orthogonal testing. The results reveal that SiC addition has the most remarkable effects on the mechanical properties of the composites

then the stirring time and stirring temperature have. In the experimental conditions

the SiCp/AZ91 magnesium matrix composites with excellent performance can be prepared by adding 6% SiC （volume fraction） with stirring at 595 ℃ for 5 min.
