Abstract: Cryogenic strength,ductility and toughness of AI-Li alloy 8090 were found to be superior to those at ambient temperature,and up to optima at about 20 K.Different aging regimes may only influence on its cryogenic yield strength and elongation.

Key words: Al-Li alloy, cryogenic mechanical property, work hardening, alloy 8090
