The impacts of alloying elements on Al-Li alloys [3], [66].

Alloying elements	Effect
Li and Mg	•Solid-solution strengthening
	•Precipitation strengthening
	•Decrease density
Cu and Ag	•Solid-solution strengthening
	•Precipitation strengthening
Zn	•Solid-solution strengthening
	•Improve corrosion properties
Zr and Mn	•Texture control
	•Govern of recrystallization
Ti	•Considered as grain refiner during ingots solidifications
Fe and Si	•Considered as impurities affecting fatigue, corrosion properties and fracture toughness
Na and K	•Considered as impurities affecting fracture toughness.
