Abstract
En 中文
• The hydrogen storage capacity of the Mg98.25Ni0.75Gd1 alloy was significantly enhanced by the addition of 0.4 at.% Ho. • The morphology, volume fraction and distribution of the LPSO phase were significantly improved by replacing part of Gd in the LPSO phase with trace Ho. • Grain refinement and LPSO phase structure regulation are the key to improving the hydrogen storage performance of alloys.
