Radiation resistance of fission and fusion structural materials is determined by such physical phenomena as radiation swelling and creep, radiation hardening, helium and hydrogen embrittlement. All these physical phenomena depend on microstructure changes in irradiated structural materials. The key problem for prolongation of life time of fission atomic reactors and for fusion reactors is to obtain some experimental data about the microstructure changes in structural materials changes at different temperatures at high doses of neutron irradiation and at high level produce displaced atoms. The experimental tests of structural materials in atomic reactors are very expensive and they take long time. The irradiation of these materials by charge fast particle beams on accelerates allow to get such experimental data for physical mechanisms of radiation resistance of them more easy during short time without high radioactivity level on irradiated samples. The some results concerning the investigation of effect of charged particle irradiation on materials are presented here.
