　　Tungsten(W)is one of the significant candidate for plasma-facing materials(PFM)in the next generation of fusion reactors.The behaviors of Deuterium(D)and tritium(T)retention and the damage in PFM will directly affect the stability of plasma and the service life of PFM.Alloying is an important method to improve the properties of W as the first wall material.In this work,we have used an ion implantation method to inject the five elements of niobium(Nb),molybdenum(Mo),chromium(Cr),deuterium(D)and helium(He)in pure tungsten,respectively.
