This is a multidisciplinary effort involving metallurgy, physics, and chemistry to explore a new approach to the processing of primary aluminum-lithium, magnesium-lithium, and copper-lithium alloys. The process employs an impinging lithium vapor on the metal surface with subsequent movement of the lithium into the alloy by solid-state diffusion. The process is unique in that it introduces the reactive element into the alloy in the final stages of the production of the wrought product. Risks involved include the ability to reach a homogeneous distribution of the diffusing lithium in a reasonably short time frame and possible problems associated with unintended oxidation of the alloy during processing.

这是一项涉及冶金学、物理学、 和化学探索一种新的方法来处理 初级铝锂、镁锂和铜锂 合金. 该方法采用冲击锂蒸气在 金属表面，随后锂移动到金属表面， 通过固态扩散形成合金。 这个过程的独特之处在于， 在最后将活性元素引入合金中， 锻造产品的生产阶段。 涉风险 包括达到均匀分布的能力， 在相当短的时间内扩散锂， 与合金的意外氧化有关的问题 处理.
