dvance in the Research of Rapidly Solidified Al-Li Alloys

(received July 9, 1993, revised Sep. 15)Yu Gulfu; Jiao Chengge; Dai Shenglong(Institute of Aeronautical Materials, Beijing 100095)  
n approch to improve ductility and toughness of RS A1-Li alloy is discussed in terms of alloying,strengthening of powder boundaries and fracture behavior. The fundamental property of low density resultsin a rapidly solidified Al-Li alloy as good as the alloy manufactured by Allied-Signal Co. (USA) throughplanar flow casting. This alloy is superior to conventional ingot metallurgy 2219 alloy commonly used inspace shuttle.
