摘要：

Ti and its alloys have a high affinity for hydrogen and are typical hydride formers. Ti-hydride are brittle phases which probably cause premature failure of Ti-alloys. Here, we used atom probe tomography and electron microscopy to investigate the hydrogen distribution in a set of specimens of commercially pure Ti, model and commercial Ti-alloys. Although likely partly introduced during specimen preparation with the focused-ion beam, we show formation of Ti-hydrides along alpha grain boundaries and alpha/beta phase boundaries in commercial pure Ti and alpha+beta binary model alloys. No hydrides are observed in the alpha phase in alloys with Al addition or quenched-in Mo supersaturation. (C) 2018 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
