The modern family of aluminum alloys has a broad range of applications. However, there are currently no aluminum alloys capable of operating at elevated temperatures while maintaining mechanical properties compatible with high performance automotive and aerospace applications. The high temperature phase equilibrium of Al-REE-X (REE-Rare earth elements and X-traditional alloying elements) is not well understood yet this class of materials shows promise as a light weight material for stiffness-driven high temperature applications. To date, we have determined RE alloys of Al to be castable across a broad range of temperatures and RE compositions. In addition, room temperature physical properties of Al-RE alloys appear to be in line with existing aluminum alloys with superior microstructural stability and associated properties at temperatures exceeding 150 °C. In this talk we will discuss the mechanical properties, microstructure, and compositional data for the new Al-RE alloys at room and elevated temperatures.
