Tungsten is the leading candidate material for plasma facing applications in future tokamak systems, due to its high melting point, good sputtering resistance and low activity after irradiation. Despite this there has been a significant lack of study of the effect of transmutation products on the post irradiation mechanical behaviour of tungsten-based alloy systems. This will be key to...

Microstructural evolution and mechanical properties of Ti-bearing RAFM steels were investigated after aging at 550 °C for 0 ~ 1000 hr. All samples with Ti were prepared using vacuum induction melting furnace and hot rolling process, followed by heat treatment in normalizing and tempering. Microstructures including precipitates, fractured surfaces and cross-sectional microsturctures were...

Tungsten is the main candidate material for the plasma facing components of future fusion devices. During operation, these components will be subject to severe conditions, involving both steady state and transient heat loads as well as high particle fluxes. These may lead to surface and structure modifications which influence their performance and lifetime. Therefore, it is necessary to study...

Material issues pose significant challenges for future fusion reactors like DEMO. When using materials in a fusion environment a highly integrated approach is required. Cracking, oxidation and 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....
