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

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