THERMAL CONDUCTIVITY OF Al-Li ALLOY AT CRYOGENIC TEMPERATURES
(Department of Materials Science and Engineering,Shandong Univesity of Technology, Jinan 250014)
Abstract: By using steady-thermal flow method, the thermal conductivity of round material bars 3 mm in diameter and 6 mm in length after solid solution treatment(830K, 1 h) were measured between 4~90 K range in continuous flow helium isothermal temperature apparatus. Some experimmental results were reported and profitable discussion about mechanism of thermal conductivity at different temperatures was made.
Key words: thermal conductivity Al-Li alloy cryogenic temperatures
