Abstract: Properties of high entropy alloys are currently in the spotlight due to their promising applications. One of the least investigated aspects is the affinity of these alloys to hydrogen, its diffusion and reactions. In this study we apply high-pressure at ambient temperature and investigate stress-induced diffusion of hydrogen into the structure of high entropy alloys (HEA) including the famous Cantor alloy as well as less known, but nevertheless important platinum group (PGM) alloys. By applying X-ray diffraction to samples loaded into diamond anvil cells we perform a comparative investigation of these HEA alloys in Ne and H2 pressure-transmitting media. Surprisingly, even under stresses far exceeding conventional industrial processes both Cantor and PGM alloys show exceptional resistance to hydride formation, on par with widely used industrial grade Cu–Be alloys. Our observations inspire optimism for practical HEA applications in hydrogen-relevant industry and technology (e.g. coatings, etc), particularly those related to transport and storage.
