Disclosed herein are embodiments of rapidly solidified alloys that comprise aluminum, a rare earth element, one or more additional alloying elements, such as aluminum, and an optional additive component. The alloy embodiments exhibit a unique microstructure as compared to microstructures obtained from other alloys that are not rapidly cooled. The disclosed aluminum-rare earth element alloys also exhibit improved mechanical properties without the need for post-processing heat treatments and further do not exhibit substantial coarsening.

Rapidly solidified aluminum-rare earth element alloy and method of making the same

Production of a bulk Al-RE alloy body (product) using cast billets/ingots (cooling rates <100 C/s) or rapidly solidified Al-RE particulates (cooling rates 10-10° C./second) that have beneficial microstructural refinements that are further refined by subsequent consolidation to produce a consolidated bulk alloy product having excellent mechanical properties over a wide temperature range such as up to and above 230° C.
