Tungsten materials are particularly expected to be used as a plasma facing material of the International Thermonuclear Experimental Reactor (ITER), since they have high heat resistance, high thermal shock resistance, high thermal conductivity, excellent erosion resistance and easy plasma control performance. On the other hand, they are low fracture toughness and hard workability, and the joining technique with cooling structures is not established yet and the effects of radiation damage on the properties and the microstructures are not researched sufficiently. In this study, tungsten materials are joined with a copper cooling structure, and high energy ions of Cu^<2+> are irradiated to the joining materials. The changes of the material properties and the microstructures due to radiation damage are evaluated by an ultra micro hardness tester, SEM and TEM.
