摘要

难熔高熵合金WMoTaNbV直接从大气中吸收大量的氢。有效的氢吸收归因于合金的元素组成及其高度精细的晶格结构。本文采用扫描电镜和离子束分析方法研究了晶粒尺寸和形貌对储氢性能的影响，发现WMoTaNbV合金的微观结构与储氢性能具有一致性。

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.
