Effects of lattice parameter changes on critical resolved shear stress and mechanical properties of magnesium binary single crystals

► CRSS of Mg binary single crystals increased mainly by friction mechanism. ► Solid solution hardening was accounted for by a new volume misfit parameter. ► YS showed mild temperature dependence, but UTS decreased rapidly with temperature. ► Basal pole intensity was stronger in Mg-Al, weaker in Mg-Li, but no change in Mg-Zn.
