A precipitation hardenable Mgâ3Gdâ3Ndâ0.6Zr alloy was designed by thermodynamic calculations firstly and then investigated by experiment. In the asâcast alloy, the solution of Nd atoms into equilibrium Mg5Gd phase facilitated its formation and increased its lattice constant. After a twoâstep solution and a twoâstep aging treatment, the alloy showed remarkable ageâhardening response, which was caused by the formation of massive fine Î²1 precipitates. It is quite possible that the Î²1 phase is a continuous solid solution with metastable Mg3Nd and Mg3Gd phases.
