Insights into the composition exploration of novel hydrogen storage alloys: evaluation of the Mg–Ni–Nd–H phase diagram

In order to provide an efficient tool to explore alloy composition and processing conditions for Mg-based alloys with good hydriding/dehydriding (H/D) properties, investigation of the Mg–Ni–Nd–H quaternary system was carried out by experimental measurements and CALPHAD thermodynamic analysis combined with first-principles calculations.
