“…Actual studies concerning b phase Mg-Li alloys focus mostly on microstructural features that can improve the mechanical properties of the mentioned materials (Ref [17][18][19][20]. It has been observed that depending on the alloying elements and type of subsequent deformation, the Al 12 Mg The most common and problematic issue, besides unsatisfactory mechanical properties of the b phase Mg-Li alloys, is their weak corrosion resistance (Ref [26][27][28]. In the present study, the design of an Mg-3Al-1Zn-15Li is described with a focus on the influence of microstructural properties on the mentioned Mg-Li alloys after conventional extrusion, and after conventional extrusion with subsequent annealing in respect to their corrosion resistance.…”

In this study, the microstructure and corrosion resistance of the as-extruded and as-extruded with subsequent heat treatment Mg-3Al-1Zn-15Li (LAZ1531) alloys have been investigated. The alloysÕ microstructures consisted of a(Mg), b(Li), H-MgLi 2 Al and Mg 17 Al 12. As a result of annealing, the b(Li) to a(Mg) transformation occurred, and the recrystallization supported the reformation of the Mg 17 Al 12. The electrochemical tests showed that the increased amount of a(Mg) and higher amount of Mg 17 Al 12 in the heattreated alloy favored reactions and determined it as having better corrosion resistance in 3.5 wt.% NaCl.
