[2G16] Development of potassium doped tungsten thick plates for fusion reactors
(2) Characterization of potassium doped tungsten thick plates
Keywords:Tungsten, Potassium doping, Grain structure, Mechanical property, Recrystallization
Tungsten material used in fusion DEMO and beyond requires the improvement of low-temperature brittleness and suppression of recrystallization embrittlement and neutron irradiation embrittlement. In this study, potassium-doped tungsten plates with an appropriate thickness of fusion reactor divertors have been developed, which can overcome these issues. In this presentation, the grain structure, mechanical properties, and recrystallization behavior of the materials will be reported.
