Effect of microstructure on hydrogen absorption in WMoTaNbV high-entropy alloy
The refractory high entropy alloy, WMoTaNbV, absorbs significant quantities of H directly from the atmosphere. The effective hydrogen absorption has been attributed to the elemental composition of the alloy as well as its highly elaborate lattice structure. In this work, we apply scanning electron microscopy and ion beam analysis tools to investigate the effect of grain size and morphology on hydrogen storage, observing a consistency between the microstructure of WMoTaNbV alloy and hydrogen absorption.
