Abstract
A method of producing metallic materials for the components of nuclear reactors is disclosed, which comprises adding a boron-=containing material having a value of .sup.11 B/(.sup.10 B+.sup.11 B) larger than that of natural boron to molten metal before deboronification refining. The resulting metallic materials are used even under neutron irradiation without causing .sup.10 B(n, .alpha.).sup.7 Li nuclear reaction.
