Effects of Particle Diameter on Microstructure and Tensile Properties of SiC Particle Reinforced Al-Si Alloy Composites by Spray Deposition
摘 要
采用喷射沉积技术制备了SiC颗粒增强铝硅合金复合材料, 研究了SiC颗粒粒径对复合材料显微组织及其拉伸性能的影响。结果表明: SiC颗粒的加入使复合材料的弹性模量高于基体合金的, 但是其抗拉强度以及伸长率降低; 挤压后复合材料中SiC颗粒分布有沿挤压方向排列的趋势, 且随颗粒粒径的增大, 趋势更明显; 与相同含量大粒径(20 μm)颗粒相比, 小粒径(4.5 μm)颗粒间距小, 颗粒承载能力大, 其复合材料表现出较高的弹性模量和抗拉强度, 断裂方式以SiC颗粒与基体界面脱离为主, 而颗粒的断裂是大粒径SiC颗粒增强复合材料的主要断裂方式。

Abstract
The effects of SiC particle diamater on the microstructure and tensile properties of spray-formed SiC particle reinforced Al-Si alloy composites were investigated. The results show that the addition of the SiC particles increased the elastic modulus, but decreased the tensile strength and elongation of the composites compared with those of the Al-Si alloy matrix. The SiC particles in both composites were partially aligned along the extrusion direction. When the diameter of SiC particle increased, the degree of orientations increased. The small SiC particles with diameter of 4.5 μm had smaller interparticle spacing and shared more portion of loading than that of SiC particles with the diameter of 20 μm. Therefore, the composites with small reinforcements were better than the composites with big reinforcements in elastic modulus and tensile strength. The interfacial debonding between the SiC particles and the matrix was the main fracture mechanism of the composites with small particles, while the cracking of the SiC particles was dominant in the composite with coarse particles.
