Abstract Scope |
The promising mechanical strength, sputtering resistance and thermal conductivity make tungsten (W) a potential candidate for future fusion plasma facing applications. However, the requirement of good combination of strength, toughness and irradiation resistance emphasize upon the requirement of innovative W-based materials. This paper presents development and analysis of a novel reduced activation W-based alloy WxTaTiVCr. We fabricated the samples by spark plasma sintering of mixture of pure elemental powders. Microstructural and mechanical properties have been analyzed via electron microscopy, compression and toughness tests, respectively. The samples were irradiated through proton irradiation, and surface morphology, sub-surface microstructure and nanoindentation hardness or irradiated and un-irradiated samples were analyzed. High voltage electron microscope (HVEM) was employed for in-situ analysis of resistance to electron irradiation. The enhanced irradiation resistance of WxTaTiVCr have been observed. |
