Magnesium rare earth (RE) alloys undergo significant strengthening during artificial aging due to the formation of solid-state precipitates with habit planes lying parallel to the prismatic planes. Although a lot of research studies have focused on precipitation in Mg-RE alloys, much work is still needed to fully characterize the physical nature of the precipitates to understand how they nucleate and grow. Therefore, this work focuses on quantifying the chemical and microstructural factors important in controlling phase stability and precipitation mechanisms in Mg-RE alloys by characterizing precipitates in model alloys including the Mg-Nd, Mg-Y, and Mg-Nd-Y systems using scanning transmission electron microscopy and atom probe tomography. The role of strains and chemistry will be discussed to explain the observed precipitate structures and their evolution during aging.
