研究了一种制备高SiCp含量AZ31镁基复合材料的分级搅拌工艺。结果表明

分级搅拌工艺制备的复合材料SiCp含量为25%

颗粒分布标准偏差小于0.1。

Abstract

The SiCp/AZ31 composites were prepared by stirring casting

and effects of stirring speed and stirring time on porosity and particle distribution in the composites prepared was investigated. The experimental results show that the process parameters

such as stirring speed

stirring time

have a marked influence on the distribution of SiCp in MMC. A method called graded stirring is proposed to overcome the low reinforcement content. Magnesium matrix composites containing 25%SiC particles with standard distribution error lower than 0.1 can be prepared successfully by the graded stirring process.
