L'hydrogène possède une faible densité volumétrique ce qui est un problème pour son stockage. Ainsi, pour pouvoir le stocker en toute sécurité, en grandes quantités et sous une pression modérée, les systèmes de stockage à l'état solide basés sur les hydrures métalliques sont considérés comme une solution très intéressante. Dans ce projet de thèse, nous étudions la caractérisation structurale et les propriétés de sorption de l’hydrogène de différents alliages à haute entropie ayant la composition Hf1-xTixNbVZr (x = 0, 0.25, 0.5, 0.75 et 1). Ces alliages ont été préparés à l'aide de deux techniques différentes : la fusion à l'arc et la fusion par induction.Notre étude a mis en évidence que la méthode de synthèse et la composition chimique ava...
