Hydrogen Retention in Tungsten Alloys Developed for Fusion Facilities (Review)

Аннотация

This review is focused on the effect of doping with various elements on retention in tungsten. Although tungsten is one of the most promising plasma-facing materials (PFMs), it still has a number of drawbacks. Doping is proposed as a way to make tungsten more suitable for PFM applications. A considerable number of tungsten alloys have already been developed in the course of fusion research. Doping may alter the parameters of hydrogen retention in tungsten, and this should be taken into account in selecting the materials for fusion facilities.
