Abstract
Measurements were made of lithium loss in an Al-3.12 mass%Li alloy during the solution treatment at high temperatures under varied atmospheres. The microstructure and the hardness distribution in the surface layer of the alloy were highly sensitive to the temperature, the period and the atmosphere of solution treatment. A considerable amount of lithium was lost in the layer within 0.3 mm from the surface during the solution treatment in this study. Lithium loss during the solution treatment at 823 K for 3.6-36 ks was minimized by Ar gas sealing. The activation energy of diffusion of lithium in aluminum was estimated at 130 kJ/mol from the analysis of the hardness distribution curves. The process of lithium loss during the solution treatment in dynamic vacuum is considered to be controlled by the diffusion of lithium atoms toward the surface from the inside of the crystal.
