Magnesium rare earth alloys form unique precipitate structures during aging that make these materials desirable for applications where a high strength to weight ratio is important. Commercial alloys such as WE43 are quite complex, making it difficult to fully understand the factors controlling precipitation in these alloys that are needed in the design of new and improved alloys. In this work, we investigate the evolution of the different precipitate phases that form in Mg-Nd, Mg-Y, and Mg-Nd-Y alloys using scanning transmission electron microscopy and atom probe tomography and relate the microstructure to the measured changes in alloy hardness via post-mortem observations of deformed alloys.
