| Abstract Scope |
Light-weight Magnesium (Mg) alloys attract great attention for automotive applications, especially in power-train components. It acknowledges the potential of rare earth elements, specifically cerium (Ce), as an alloying addition to enhance the mechanical properties of Mg alloys at both room and high temperatures. However, its precise role is not yet well understood, particularly regarding nano-scale phase transformations, interface-solute segregations, and their effect on mechanical behaviour. Additionally, the literature suggests that dilute Mg-Ce alloys are not precipitation hardenable. To address this knowledge gap, the present work focuses on the design of dilute Mg-Ce based alloys with further alloying addition of Gd for high temperature applications. More specifically, we investigate the structural evolution of strengthening metastable and stable precipitates and their influence on their mechanical properties. |
