    Abstract

    In an attempt to improve the hydrogenation kinetics properties of Mg-based materials, a novel Mg65Ce10Ni20Cu5 nanoglass was fabricated by melt spinning followed by severe plastic deformation through the high-pressure torsion (HPT) method. The hydrogenation temperature of the nanoglass was greatly reduced with significant improvements on the hydrogenation kinetics upon three different HPT treatments. The 1 turn HPT-treated alloy shows the best hydrogenation properties with the highest capacity and fastest kinetics among the three samples. These superior hydrogenation properties were attributed to the HPT-induced abundant nanoglasses regions and interfaces among them, as pathways for hydrogen absorption.
