Enhancement of Hydrogen Storage Properties of AlTiVCr Light Weight High Entropy Alloys (HEA) by Ti3C2 Mxene and Several Plastic Deformation (EHSAL)
Annotation in Czech
Recently discovered AlTiVCr high entropy alloy (HEA) exhibits about 70x increase in equilibrium pressure and approximately 20 kJ per mol H2 decrease in desorption enthalpy (H) relative to the benchmark TiVZrNbHf HEA possessing H to M ratio bigger than 2 with 2.7 wt- percent hydrogens at 53 bar (H2). The AlTiVCr HEA desorption enthalpy H is approximately 40 kJ per mol and H to M ratio approximately 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 to 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 H, higher H to M ratio and faster kinetics.
