Material issues pose a significant challenge for future fusion reactors like DEMO and highly integrated approach is required. Cracking, oxidation as well as fuel management are driving issues when deciding for new materials. Neutron induced effects e.g. transmutation adding to embrittlement are crucial to material performance. Here advanced materials e.g. Wf/W composites allow the step towards a fusion reactor. Recent developments in the area of Wf/W will be presented showing a possible path towards a component based on standard tungsten production technologies. Damage resilient materials, with an increased operational temperature range facilitate component design with higher exhaust capabilities. The maximization of operational performance can only be achieved, if improvements of material properties, mechanical and thermal, are well balanced Wf/W contributes here to advanced material strength and crack resilience even after embrittlement. Rigorous testing with respect to plasma-wall-interaction and high heat-flux performance are ongoing. Prototype components are envisioned in the near future.

Plasma facing materials (PFMs) in a fusion device like ITER/DEMO have to withstand severe environmental conditions such as high thermal loads and particle fluxes. These exposure conditions may cause a deterioration of the heat removal capability of the material and/or component. In order to ensure that designs of plasma facing components are suitable for an application under such exposure conditions detailed qualification programs are required. Especially the high steady state and transient thermal loads, simulated with electron/laser beams and linear plasma devices, induce a wide range of surface modifications and damages on the PFM surface as well as in the component. Important issues are the performance of materials under high cycle transients, after/during neutron irradiation, after recrystallization, and under simultaneous particle fluxes (D/T/He).
