“…6,7 With the addition of Li, the c/a ratio decreases from 1.624 (pure Mg) to 1.607 (Mg-17 at.% Li), from which the non-basal slips are operable. 8–14 Previous work has shown that prismatic slip was prevailing in Mg-Li alloy with increasing lithium contents. 9 When the Li content in Mg ranges from 17 to 30 at.%, the body-centred cubic (BCC) β-lithium phase appears, which improves the formability of Mg alloys dramatically at ambient temperatures.…”

“…16 The tensile test results indicated that the Mg-Li alloy exhibited superplasticity at 50°C, and the ductility of the alloy can reach 330% under the strain rate of 10 −2 s −1 when the temperature increases to 100°C. Ji et al 12 investigated the low-temperature superplasticity of Mg-10%Li-1%Zn alloy during the equal channel angular extrusion process. The alloy exhibited an elongation of 391% at a strain rate of 10 −3 s −1 and a temperature of 150°C.…”

Magnesium-lithium (Mg-Li) alloys, due to their high specific strength, have great potential in the modern aviation industry. The superplastic characteristics, microstructure evolution, mechanical properties, and forming process of LZ91 Mg-Li alloys at 200°C–300°C were studied in this paper. Tensile tests show that the optimal elongation of tensile specimens is 812.6% at 300°C under a strain rate of 5 × 10−4 s−1. The flow stress of the material increases with strain during the high-temperature tensile testing due to the grain coarsening . Meanwhile, low dislocation densities were observed during tension, which is not sufficient for dynamic recrystallisation to occur. The finite element method is used to investigate the forming schemes of a narrow-mouth box component. Finally, this component was manufactured by the powder pressure bulging process at 300°C experimentally.
