摘要

采用反复塑性变形（RPW）技术

结合挤压工艺制备出SiC颗粒增强AZ31镁基复合材料

研究了循环次数（RPW次数）对SiCp/AZ31镁基复合材料显微组织和性能的影响。结果表明

反复塑性变形具有明显的AZ31基体晶粒细化、SiCp细化和分散作用

能显著提高SiCp/AZ31复合材料的抗拉强度和硬度

并改善其塑性。在SiCp的体积分数为4%时

经RPW为300次的热挤压后

AZ31基体晶粒粒径达到最小值20μm

SiCp被粉碎成3μm以下的微粒

且弥散分布于合金基体中

复合材料的室温抗拉强度和硬度（HV）达到或接近最大值

分别为359MPa和107。

Abstract

SiC particulate reinforced magnesium matrix composites SiCp/AZ31 were successfully prepared by repeated plastic working（RPW）combining with hot extrusion.Effects of cycling’s times（times of RPW）on microstructure and properties of the composites were investigated.The results indicate that the RPW can refine grain sizes of AZ31 alloy and SiC particles

and uniformly distribute the SiC particle in the matrix alloy.In addition

it can not only remarkably enhance tensile strength and hardness of the composites

but also improve its plasticity.With 4% SiC particle in volumetric fraction

the ambient tensile strength and hardness of the composites can reach up to 359MPa and 107

respectively

after 300 times RPW cycling by hot extrusion

in which grain size of the matrix alloy is refined to 20 μm and SiC particles are refined to below 3 μm

dispersedly distributed in the matrix alloy.
