Low Cost, High Strength and Ductile Mg Alloys Enabled by Guinier-Preston (GP) Zones
As the lightest of all structural metals, Mg alloys have great potential where weight is critical to performance and efficiency, yet Mg alloys remain underutilized. This project explores a solution to address processing costs while simultaneously improving strength and ductility. There are many new Mg alloys with dramatically improved properties, however, these alloys typically contain rare earth elements, which are expensive and/or strategic liabilities. An alternative approach is inspired by the success story that enabled Al alloys, strengthened by nanoscale precipitates composed of elements widely available in the earth’s crust, to literally power the birth of aviation.
