摘要: Vanadium alloys are recognized as attractive candidate materials for the structural component of fusion reactors because their low activation properties, high thermal stress factors, and radiation resistance. V–4Cr–4Ti has been regarded leading composition. Recent Japanese, US, Russian, Chinese programs largely enhanced fabrication technology vanadium alloys. Also, fundamental understandings effects interstitial impurities (C, N, O) on mechanical microstructure compatibility in various environments were advanced recently. The neutron irradiation with transmutant helium properties irradiation/thermal creep performance among major remaining issues.
