Abstract
This study explored the consequences of incorporating Sc and Zr into hypoeutectic Al�e cast alloys specifically investigating their influence on microstructure and mechanical properties. The findings demonstrated the significant reduction in the grain size of the Al�e alloy while successfully maintaining the distinctive shape of the eutectic Al11Ce3 phase through the incorporation of Sc and Zr additions. During aging treatments Al3(Sc Zr) coherent precipitates formed both at the interface between the ?-Al and Al11Ce3 phases and within the ?-Al matrix. Remarkably this led to optimal hardness achieved within a short duration of 3 h at 350 ?C. Peak-aged quaternary Al�e杧Sc杫Zr alloys showed significantly better tensile strength than the binary Al朇e alloy at both ambient and elevated temperatures. Overall the study underscored promising prospects of Al朇e朣c朲r alloys for use in high-temperature applications as they exhibited enhanced mechanical properties. ? 2023 The Authors
