“…The near-surface depletion ofthe lithium can dramatically alter the mechanical behavior of the Al-Li alloy. The presence ofPFZ's have been found to have a detrimental effect on the mechanical strength, fracture behavior and stress corrosion cracking resistance of the AI-Li alloy [5]. Therefore, for any application involving the use of the alloy as a load bearing structural material, or as an area exposed to frequent wear, the near-surface depletion is of concern.…”

“…O acréscimo de Mg e Cu resulta no precipitado intermetálico S'(Al 2 CuMg), (Al 2 CuLi), que melhora a resistência mecânica e minimiza a formação da zona livre de precipitados (Jata et al, 1986). Segundo Deng (2014) e Radmilovic et al (1988), a zona livre de precipitados está relacionada com a exclusão de átomos ao redor do contorno de grãos. Isso ocorre devido à presença do Li, que reduz o número de vacâncias móveis, dificultando a formação de precipitados nos contornos de grãos (Deng, 2014).…”
