Multifunctional Ultra-Light Mg-Li Alloy Nanocomposites

Abstract

Magnesium-lithium (Mg-Li) alloys are attractive lightweight materials for many structural components of aircraft due to their high strength-to-weight ratio. They are also attractive as Li-ion battery anodes due to their high capacity and long lifetime. This multi-functionality may allow a Mg-Li airframe to serve as an energy source or peak power source for various aerial vehicles. Micro-crystalline Mg-Li alloys prepared using classical metallurgy methods exhibit low fracture toughness. Amorphous and nanocrystalline Mg-Li alloys are expected not to have this limitation. However, they have never been produced and investigated. We proposed to perform such an investigation and additionally synthesize a novel ultra-light high strength material with high energy/high power electrical energy storage capability based on a Mg-Li with carbon fiber reinforcements.
