【Abstract】

<正>Tungsten(W) is considered as the most promising plasma-facing materials(PFM) for both the diverter and the first wall in the fusion reactor.However,as a PFM,W will be subject to high flux bombardments of H isotope ions.The interaction of H and defects with microstructure in W will strongly affect intrinsic mechanical properties
