“…A higher probability of a non-basal slip reduces also the flow stress necessary for deformation of polycrystals. Haferkamp et al [8] studied microstructure and mechanical properties of superlight Mg-Li alloys. They estimated that Al content substantially increases the yield stress, maximum stress and ductility at room temperature.…”

“…The α-phase is Mg(Li) solid solution and exhibits moderate strength and low formability while the β-phase is Li(Mg) solid solution possessing excellent ductility but poor creep resistance. Therefore, dual-phase α + β structure shows an interesting properties compromise combining the moderate strength of α-phase and excellent ductility of β-phase [3]. That is why dual-phase structured Mg-Li alloys belong to prospective engineering materials, particularly for aerospace applications.…”

Proof stress Rp0.2 of dual-phase α + β structured Mg-Li and Mg-Li-Zn alloys has been inspected in terms of the strengthening contributions of α-and β-phases. The alloys studied with a variable fraction of α-and β-phases have been subjected to compression straining tests, microhardness measurements and structural analysis by EDX and XRD. Alloying with 1.5 wt.% Zn results in the hardening of both α-and β-phases which however exhibit different hardening responses due to different Zn enrichment. The rule of the mixture has been used to interpret Rp0.2 values by taking into account the fraction of α-and β-phases and their strength level represented by their microhardness. Compression stress-strain curves indicate that work hardening of alloys studied depends considerably on the fraction of α-phase and is higher for Zn-containing alloys.K e y w o r d s : Mg-Li, Mg-Li-Zn, dual-phase alloy, solution hardening, ageing, work hardening

“…The Mg-4Li alloy has hcp structure. The addition of Li to Mg increases the critical resolved shear stress (CRSS) for basal slip; the solid solution hardening is observed [7]. The CRSS of Mg4Li is almost independent on the temperature above room temperature while the CRSS for non-basal slip decreases with temperature below 200 °C as shown in [8].…”
