Abstract

In the present work, in situ Al₂O₃/Al composite was produced via CuO/Al composite and subsequent remelting, and the chemical reaction evolution and the fractography were investigated by means of differential scanning calorimeter (DSC), X-ray diffraction (XRD), electron probe micro-analysis (EPMA) and scanning electron microscopy (SEM). The experimental results showed that Al₂O₃ could be successfully formed in situ by the addition of CuO to aluminum. The results also suggested that the fracture mechanism changed from interfacial debonding in copper oxide/Al composite to particle cracking in Al₂O ₃/Al composite, which was largely attributed to interfacial bonding increased between in situ Al₂O₃ particle and Al. The Cu-O stability in the present processing was also discussed from the point view of thermodynamics.
