Lightweight alloys with high specific-strength are an essential prerequisite in modern and future technologies. To be useful, they must also possess ductility and inherent corrosion resistance. The latter two properties, however, are inversely correlated with strength. This project proposes to break this paradox - not only in terms of a paradigm change regarding multi-property alloy design - but as applied to the most lightweight engineering alloy system in existence, Magnesium-Lithium (Mg-Li), for which the impact on specific properties is immense. The aim is to develop ultra-lightweight Mg-Li based alloys with formidable property profiles via alloy design and thermomechanical processing. The expected outcome is a new class of structural corrosion resistant metal.

具有高比强度的轻质合金是现代和未来技术的基本先决条件。为了有用，它们还必须具有延展性和固有的耐腐蚀性。然而，后两种性质与强度呈负相关。该项目旨在打破这一悖论-不仅在多性能合金设计的范式变化方面-而且应用于现有最轻质的工程合金系统镁锂（Mg-Li），对特定性能的影响是巨大的。目的是通过合金设计和热机械加工开发具有强大性能的超轻质Mg-Li基合金。预期的结果是一种新型的结构耐腐蚀金属。
