Mg 2 FeH 6 - and Mg 2 CoH 5 -based composites with in situ formed YH 3 and Mg 2 NiH 4 nanoparticles were synthesized by ball milling of Mg 10 YNi + 4Fe (in mole ratio) and Mg 10 YNi + 4Co powders, respectively, at 4 MPa H 2 followed by hydrogenation at 673 K for 60 h under a hydrogen pressure of 7 M...
