Abstract The present contribution highlights results of the recent irradiation campaigns applied to screen mechanical properties advanced tungsten and copper-based materials—main candidates for application in plasma-facing components (PFC) European DEMO, which has also been presented at 28th IAEA fusion energy conference. main challenges formulated programme were linked to: (I) assessment ductile-to-brittle transition temperature newly developed tungsten-based materials; (ii) investigation...
Severe plastic deformation of tungsten (W) is known to be an efficient way reduce its inherently high ductile-to-brittle transition temperature (DBTT), what essential for use in components a fusion reactor. Thin rolled W foils possess superior mechanical behaviour at room (RT), as demonstrated previous works. It was then proposed expand the beneficial properties foil bulk by fabricating tungsten-copper (W-Cu) laminate composites, which can used structural applications. Neutron irradiation...
Abstract Development of refractory metals for application as plasma-facing armour material remains among priorities fusion research programmes in Europe, China and Japan. Improving the resistance to high temperature recrystallization, enhancing strength sustain thermal fatigue cracking tolerance neutron irradiation are key indicators used down selection materials manufacturing processes be applied deliver engineering materials. In this work we investigate effect on mechanical properties...
The interaction of carbon atoms with point defects and the core edge screw dislocations Burgers vector a0/2⟨111⟩ in W a W-Re matrix is studied by means ab initio calculations. structure energetics ground-state atomic configurations are presented rationalized. It found that di-vacancies, which thermally unstable pure according to state-of-the-art calculations, can nucleate at C Re-C complexes, fill gap explanation emergence nanovoids observed experimentally under irradiation. Also, on basis...
