Multi-scale and spatially resolved hydrogen mapping in a Ni-Nb model alloy reveals the role of the 8 phase in hydrogen embrittlement of alloy 718 KU Leuven
© 2016 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. We investigated the hydrogen distribution and desorption behavior in an electrochemically hydrogen-charged binary Ni-Nb model alloy to study the role of δ phase in hydrogen embrittlement of alloy 718. We focus on two aspects, namely, (1) mapping the hydrogen distribution with spatial resolution enabling the observation of the relations between desorption profiles and ...
