Individual contributions of gadolinium and yttrium to age hardening and high temperature strength of magnesium alloys containing both elements are investigated using alloys containing different Gd : Y mole ratios of 1 : 0, 1 : 1, 1 : 3, and 0 : 1 with a constant Y + Gd content of 2.75 mol %.

Simulations have highlighted the preference for local ordering in some high entropy alloys and, when the enthalpies of formation are combined with terms for configurational entropy, transition temperatures between order and disorder can be estimated .-allowing one to understand when effects like age hardening and degradation of an alloy's mechanical properties may be an issue.
