摘要
The process of aging precipitation in SiC<sub>p</sub>/6061 and Al<sub>2</sub>O<sub>3</sub>/6061 composites were investigated. Hardness testing, differential scanning calorimetry（DSC） and transmission electron microscopy were employed. Results showed that the precipitation phase form directly along dislocation lines in the composites because the particles produce high densities of dislocations which makes vacancy densities in the composites decrease, and the main precipitation phase at peak hardness was β′ phase.
