High‐temperature treatments of niobium under high vacuum, dilute air‐ and nitrogen‐atmospheres as investigated by in situ X‐ray absorption spectroscopy

Klaes, Jonas; Rothweiler, Patrick; Bornmann, Benjamin; Wagner, Ralph; Lützenkirchen-Hecht, Dirk (Journal of Synchrotron Radiation, 2020-12-18)

Niobium metal foils were heat‐treated at 900°C under different conditions and in situ investigated with time‐resolved X‐ray absorption fine‐structure (EXAFS and XANES) measurements. The present study aims to mimic the ...
