摘要

•Mg-Ni-Gd-Y-Zn-Cu alloys are prepared by Direct Chill (DC) casting and extrusion.•The extruded alloy excels in the hydrogen storage performance.•Extrusion refines the microstructure facilitating hydrogen ab/desorption.•LPSO phases in-situ decomposed into nanoparticles as influenced by hydrogen.
