Advanced tungsten materials for plasma-facing components of DEMO and fusion power plants
Abstract
Development of W-fibre enhanced W-composites incorporating extrinsic toughening mechanisms. Production of a large sample (more than 2000 long fibres) for mechanical and thermal testing. Even in a fully embrittled state, toughening mechanisms are still effective. Emissions of volatile W-oxides can be suppressed by alloying W with elements forming stable oxides. WCr10Ti2 has been successfully tested under accidental conditions and high heat fluxes.
