Аномальная подвижность протяженных дефектов в ниобии при электрохимическом насыщении водородом

Abstract

A goal of observing the extended defects mobility in niobium under its electrochemical loading by hydrogen was pursued in this study. Polycrystalline and single-crystalline samples of niobium were investigated near the temperature of phase transition in the system niobium-hydrogen. Obtained electrochemical, metallographical and X-ray data have shown that the processes of cooperative transport of hydrogen and spatiotemporal selforganization are implemented, which leads to anomalous enhancing of the extended defects mobility and to enhancing perfection of samples real structure.
