摘要

Vanadium alloys(V-Cr-Ti series)are important candidate materials for blanket components of fusion reactors due to their low activation and high strength at elevated temperatures.Low-temperature irradiation embrittlement determines the operation temperature limit of Vanadium alloys for the application to structural materials of fusion reactors irradiation response of vanadium alloys needs to be clarified for their application.In the present study,specimens of two alloys(V-4Cr-4Ti and V-5Cr-5Ti)were irradiated with energetic He ions and heavy ions to understand hardening of the alloys due to helium accumulation and cascade damage production.
