ALLOY RESISTANT TO IRRADIATION WITH NEUTRON AND ITS USE

摘要

PROBLEM TO BE SOLVED: To produce a Ti-base alloy for nuclear reactor and nuclear fusion reactor excellent in resistance to embrittlement by irradiation with neutrons. SOLUTION: This alloy resistant to embrittlement by irradiation with neutrons is made of a Ti alloy contg. 30-40% Al and having <=2μm average grain diameter. One or more among 1-6% Mn, 0.1-1% Si and 4-16% V may further be contained. This alloy is used as the material of an internal member of a nuclear reactor and a member irradiated with neutrons for a nuclear fusion reactor.
