Aluminum Cerium alloys offer many benefits over traditional aluminum alloys. They exhibit: good mechanical properties at ambient temperature; exceptional mechanical properties at high-temperature when compared to existing alloys; and are highly castable via traditional foundry methods. Furthermore, some newly cast compositions of Al-Ce-X alloys appear to not require heat-treatment considering their as-cast properties are sufficient for some end-user application. In this talk we will discuss recent developments in the characterization of the Al-Ce-X alloy family. Phase by phase load partitioning has been measured via neutron diffraction at the SNS Vulcan User Facility. Microstructure evolution at elevated temperatures has been studied using Small angle X-ray (SAXS and μSAXS) scattering. In addition, high temperature mechanical properties have been measured for multiple binary, ternary, and quaternary alloy compositions at temperature up to 300 °C and compared with existing alloys.
