| Zusammenfassung: | Cold-rolled tungsten with high degrees of deformation exhibits exceptionally high ductility. However, the required ultra-fine-grained microstructure is thermally unstable. A promising stabilization approach is offered by potassium doping, the potential of which was comprehensively analyzed and qualified as part of this work. K-doped tungsten could significantly improve the technical possibilities for components of future fusion reactors under heavy thermal loads. |
