研究了Y和Ce复合添加对轧制态Mg-8Li-1Al （LA81）合金组织、力学性能和各向异性的影响。Y和Ce的复合添加通过固溶强化、弥散强化和晶粒细化强化提高了合金的力学性能，塑性损失小。Mg-8Li-1Al-0.6Y-0.6Ce （LA81-0.6Y-0.6Ce）具有较好的力学性能，且几乎呈各向同性。拉伸强度为278.7 MPa，延伸率为15.0%。与LA81合金相比，其抗拉强度提高了约17.6%，伸长率仅降低3.5%，且其抗拉强度和伸长率具有良好的各向同性（射线值，接近1）。(C) 2019出版，Elsevier Ltd代表the Journal of Materials Science & Technology.h编辑部出版
The effects of combined addition of Y and Ce on the microstructure, mechanical properties and anisotropy of as-rolled Mg-8Li-1Al (LA81) alloy were studied. The combined addition of Y and Ce improves the mechanical properties with a low plasticity loss by solution strengthening, dispersion strengthening, grain refinement strengthening. Mg-8Li-1Al-0.6Y-0.6Ce (LA81-0.6Y-0.6Ce) has better mechanical properties and shows an almost isotropy. It possesses an ultimate tensile strength of 278.7 MPa and an elongation of 15.0%. Compared to LA81 alloy, the ultimate tensile strength increases by about 17.6% with an elongation reduction of only 3.5%, and a good isotropy of ultimate tensile strength and elongation (the value of ray, is near 1).
