Dislocations mediate hydrogen retention in tungsten

    Research outputpeer-review


    In this letter, a comprehensive mechanism for the nucleation and growth of bubbles on dislocations under plasma exposure of tungsten is proposed. The mechanism reconciles long-standing experimental observations of hydrogen isotopes retention, essentially defined by material microstructure, and so far not fully explained. Hence, this work provides an important link to unify material’s modelling with experimental assessment ofWandW-based alloys as candidates for plasma facing components.
