摘要

Tungsten(W)is a promising candidate as the plasma-facing materials in fusion reactors,which suffers from helium(He)from the nuclear reaction,etc.The optimized dispersion-strengthened tungsten possesses better mechanical strength and toughness and is more resistant to irradiation than pure tungsten.However,there are few researches on the defects and properties in irradiated dispersion-strengthened tungsten,and the effects of dispersoids on the irradiation-induced defects are still unclear.
