Annotation:Recently discovered AlTiVCr high entropy alloy (HEA) exhibits about 70x increase in equilibrium pressure, ~20 kJ/mol H2 decrease in desorption enthalpy (ΔH) relative to the benchmark TiVZrNbHf HEA possessing H/M ratio > 2 with 2.7 wt % hydrogens at 53 bar H2. The AlTiVCr HEA desorption enthalpy ΔH is ~40 kJ/mol and H/M ratio ~1. Since AlTiVCr alloy includes lighter-weight elements relative to earlier studied refractory HEAs, it is envisaged that AlTiVCr can be a potential lightweight metal hydride for future hydrogen storage application if its H/m ratio and hydrogenation/dehydrogenation kinetics can be improved. So far, the addition of Mxene (Ti3C2) as catalyst and nanosizing exhibited a significant influence on the kinetics and hydrogenation capacity of Mg metal hydrides independently. Therefore, in this study, we aim to develop a lightweight metal hydride composite of AlTiVCr HEA by the combination of three concepts of HEA, Mxenes (Ti3C2 Mxene) and nanosizing by high-pressure torsion (HPT). The influence of Mxene and deformation heterogeneities will be investigated and will be tailored for achieving lower ΔH, higher H/M ratio and faster kinetics.
