Abstract Scope |
Recent studies have shown that aluminum-cerium based alloys could find applications in the aerospace and automotive industries due to their good castability and microstructural stability at elevated temperatures. The size and morphology of the Al11Ce3 intermetallic phase, which forms upon eutectic solidification and could be influenced by the cooling rate, affect the mechanical properties of these alloys. In this work, to study the variations in the mechanical properties with respect to the cooling rate during solidification, several binary, ternary, and quaternary alloy systems are created using different fabrication techniques, including conventional casting, arc melting, and laser powder bed fusion, that span several orders of magnitude in cooling rates. The effect of cooling rate is then studied through microstructural characterization, microhardness measurements at room temperature, and high-temperature tensile testing. |
