“…Co is added to improve the cycle life by reducing the lattice expansion during hydriding and to result in less pulverization [27][28][29][30][31]. The addition of Al improves the cycle life by forming a dense oxide film on the alloy surface [32][33][34][35]. Mn plays an important role in balancing the ratios of phases co-existing in the alloy and therefore improves the cycle life by a proper optimization in composition [36,37].…”

“…Alloying with aluminum (Al) has found widespread applications in various hydrogen storage alloy systems, including AB 5 , superlattice A 2 B 7 , V-based solid solutions, and Mgbased alloys [27][28][29][30][31][32]. Notably, Mg-Al intermetallics such as Mg 17 Al 12 and Mg 2 Al 3 have been identified for their capacity to engage in reactions with hydrogen, thereby enhancing the decomposition kinetics of MgH 2 [33][34][35][36].…”

Mg80Ni16−xAlxY4 (x = 2, 4, 8) alloys were prepared by induction levitation melting, and the effect of substitution of Al for Ni on the microstructure and hydrogen storage properties was studied in the present work. The results illustrated that the solidification path, phase constitution, and grain size were significantly altered by Al addition. Appropriate Al addition improved abundance and grain refinement of the Mg, Mg2Ni, and Mg15NiY ternary eutectic. But as Al further increased, Mg solidified independently rather than in the formation of the ternary eutectic. More Al favored the formation of Al3Ni2Y but suppressed Mg2Ni and YMgNi4. Although the hydrogen absorption activation and the kinetic property deteriorated, the thermodynamic stability of hydrides was enhanced by adding Al. Hydrogen absorption ability under low pressure was improved, and the Mg80Ni8Al8Y4 alloy could absorb nearly 3.5 wt% hydrogen under 1 bar hydrogen at 250 °C.
