The lowest growth temperature limit to obtain the highest rotational variety, without compromising the structural quality, is determined by low energy electron diffraction (LEED) and scanning tunneling microscopy (STM).

The structure of Cl adsorbed on the Al matrix at the Al (111)/Al<sub>3</sub>Li (111) interface is the most stable, with an adsorption energy of −2.54351 eV. Under 1 %-5% strain, the electron cloud distribution at the interface does not change significantly.

Tensile and electrochemical experiments indicate that the corrosion rate of the sample under 2 % strain is the lowest (1.0374 mm/a), and the angle value in the low-frequency region changes from 10.623° to 19.57° under 2 % strain, with the largest variation degree, exhibiting the best corrosion resistance. SEM observation of the corrosion morphology shows that the corrosion evolves into intergranular corrosion, and during the corrosion process, intergranular corrosion develops into pitting corrosion, with a large amount of Cl ions adhering to the corrosion pits, leading to spalling of the material surface.
