Advances in the research of tungsten-based plasma materials in fusion reactors.

Abstract:

Tungsten-based materials with high melting point, high thermal conductivity, low vapor pressure and low tritium retention have become plasma oriented materials with broad application prospects. Due to its shortcomings in low temperature brittleness, recrystallization brittleness and irradiation damage, its application in engineering is limited, and it has become a research hotspot in the field of nuclear fusion materials. In this paper, the research status of tungsten-oriented plasma-oriented materials is reviewed, the damage caused by four kinds of particle irradiation and four kinds of commonly used methods to improve the properties of tungsten materials are described, and the problems that need to be solved are also discussed.
