摘要
含Sc铝锂合金具有高的比强度、比刚度、塑韧性以及优异的焊接性能、低温性能和较低的各向异性,是新一代航天、航空用轻质铝合金结构材料。作者在查阅大量文献和赴俄罗斯考察的基础上,结合课题组研究工作,介绍了国内外含Sc铝锂合金研究发展情况,并提出了今后研究开发的方向。
Sc containing Al-Li alloys possess high specific strength, specific stiffness, ductility toμghness and very good weldability,low temperature property and lower anisotropic property, and is a new light structural material used in aerospace and aviation. Based on large amount of references and investigation in Russia and combined with the research work done by the group of this task,at home and abroad research of recent developmental situation of Sc containing Al-Li alloys is introduced, and the research direction is proposed.
