Abstract:In the operation of a fusion reactor, the tungsten-based material needs to withstand a certain number of steady-state and transient-state heat load impact without cranking, melting and other damage. The damage behavior of commercial tungsten under different test conditions was analyzed. The effects of modification methods, such as superfine grain tungsten, alloying, doping carbide and rare earth oxides, on the heat load performance of tungsten-based materials were discussed. The research on heat load damage of plasma tungsten-based materials was summarized and forecast.
Key words: tungsten based materials; plasma facing material; heat load; second phase doping; superfine grain tungsten
