采用快速凝固粉末冶金法（ＲＳ／ＰＭ）制备Ａｌ－Ｌｉ－Ｍｇ－Ｃｕ－Ｚｒ合金（合金经固溶时效处理）．测试了合金的拉伸性能，并借助于ＳＥＭ、ＴＥＭ探明了该合金的时效强化机理．
Al-Li-Mg-Cu-Zr alloy was prepared by rapid solidification powder metallurgy (RS / PM). Tensile properties of the alloy were tested, and the aging strengthening mechanism of the alloy was proved by means of SEM and TEM.
