Abstract: During the operation of nuclear fusion reactors, plasma facing tungsten-based materials need to withstand a certain number of times of steady-state and transient heat load without cracking, melting and other damage. This paper mainly summarizes the effects of alloying, dispersion strengthening and other modification methods on the thermal load damage behavior of tungsten-based materials. The heat load damage behavior of plasma facing tungsten-based materials was summarized and prospected.
