Diffusion Controlled Lithiation of Metals and Metallic Alloys

这是一项涉及冶金、物理和化学的多学科努力，旨在探索加工原铝锂合金、镁锂合金和铜锂合金的新方法。该工艺采用撞击金属表面的锂蒸气，随后锂通过固态扩散进入合金。该工艺的独特之处在于它在锻造产品生产的最后阶段将反应性元素引入合金中。所涉及的风险包括在相当短的时间内达到扩散锂均匀分布的能力，以及在加工过程中合金意外氧化的可能问题。

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.
