Abstract
Changes of the defect structure of niobium induced by hydrogen loading are presented in this work. The evolution of the microstructure with increasing hydrogen concentration was studied by X-ray diffraction and two complementary techniques of positron annihilation spectroscopy (PAS). A comparison of PAS results with theoretical calculations revealed that complexes consisting of a vacancy, surrounded likely by four hydrogen atoms, were introduced into the samples due to hydrogen loading.
Keywords: hydrogen; niobium; vacancies
