Abstract: Aging behaviors of submicron Al2O3P/6061 composite were investigated by Vickers hardness (HV) measurement and transmission electron microscope (TEM) observation. The results showed that there was an idiographic microstructure and aging characteristic in the composite. Addition of fine Al2O3 particulates would strongly restrain the precipitation and reduce the thermal mismatch dislocation density due to the difference of coefficient of thermal expansion (CTE) between the matrix and the reinforcemertt.
