In magnesium-based systems, stable disordered bcc phases are only known to exist in Mg-Li based alloy systems. However, it is known that Mg is an intense stabiliser of high temperature beta-rare earth phases (also disordered bcc) which often have a high solubility of Mg which can be sustained via quenching. This work focuses on stabilising Mg-rich beta-rare earth phases through targeted alloying additions of specific rare earth elements to generate more stable beta and alpha plus beta Mg-based alloys. The mechanical properties present a large variation across small changes to the composition allowing for targeting desired properties for specific light weight applications.
