The microstructural characteristic of 1070Al matrix composites reinforced by 0.15µm Al2O3 particles whose volume fraction was 40% was investigated by TEM and HREM. The results showed that the interface between the matrix and reinforcements was clean and bonded well, without any interfacial reaction products. There were some preferential crystallographic orientation relationships between Al matrix and Al2O3 particle because of the lattice imperfection on the surface of Al2O3 particles.

将Ce添加在Al2O3 p/Al复合材料中,采用Axiovert25CA金相显微镜和QUANTA400扫描电镜,研究了Ce含量对Al2O3p/Al复合材料铸态组织的影响.结果表明,Ce的加入可以促进Al2O3颗粒的分散、细化α-Al晶粒、使AlFeSi由粗大骨骼状变为断续的块状或球状,可以提高复合材料的强度.
