This review considers some of the urgent material problems connected with the construction and operation of fusion devices and future commercial fusion reactors. Reference is made to research programmes both within the European Community and elsewhere. Plasma disruptions, a high heat load and irradiation effects cause problems such as surface erosion, crack formation, fatigue, creep, H-embrittlement and general thermal and mechanical stress in reactor components. The materials used include graphite, beryllium and various steels for walls, copper coils, copper alloys for divertor plates, ceramics for optical windows and magnetic materials. Low activation materials are required for the blanket and shielding materials. Electron microscopy can be decisive in the choice of radiation damage resistant materials which satisfy the required mechanical and corrosion properties.
