摘要

Hydrogen embrittlement is one of the key issues for the vanadium alloys for fusion application. Previous study has shown that V4Ti alloy had better properties against the embrittlement than V4Cr4Ti and V4Ti3A1 alloys. It was thought that the better property was benefited from the small ratio of itsyield strength over its ultimate tensilestrength.
