Abstract
A methodology to control the interfacial microstructures, while suppressing the formation of Al₄C₃ in wrought Al alloy composites reinforced with SiC, was demonstrated. Thermodynamic calculations were carried out to elucidate how one can select process parameters in terms of alloy composition and fabrication temperature to obtain intended interfaces. Experimental verifications were conducted using SEM and TEM to validate calculated results. The reaction mechanisms for forming various interfaces were identified both theoretically and experimentally. The evaluations of the interfacial bonding strengths and interfacial stability, at elevated temperatures were carried for various interface type.
