The phenomenon of return consisting in softening after hardening aging at 200°C for a duration from 0.5 to 128 h in the case of short-term (from 0.25 to 64 h) subsequent annealing at a slightly higher temperature of 250°C in magnesium alloys with yttrium (Y) additionally doped with samarium (Sm) was studied. Both alloying elements are rare earth metals (REM), but belong to different groups: Y belongs to the yttrium group and Sm belongs to the cerium group. It was found that, both in the double alloy Mg–Y and in the alloy of the ternary system Mg–Y–Sm, there is a return phenomenon. The addition of samarium to the Mg–Y binary alloy and an increase in its content within the studied range from 0.6 to 1.8% leads to an increase in the return, but at the same time, the effect of hardening of alloys during previous aging also increases to a greater extent, which overlaps in magnitude the softening effect on return.
