EFFECTS OF La ON STRUCTURES AND PROPERTIES OF Al-Mg-Li ALLOY
La对Al—Mg—Li合金组织和性能的影响

The effects of La on structures and properties of Al-Mg-Li alloys were in-vestigated.Experiments results show:at peak aging condition,strength and elongation in-crease in the Al-5Mg-2.4Li alloy added by rare earth element La,which is resulted fromthe refi
