Abstract

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.
