PROBLEM TO BE SOLVED : To provide a dual phase alloy for separating/refining hydrogen having excellent hydrogen separability and hydrogen embrittlement resistance without using Pd as an expensive noble metal, and usable at high temperature.
SOLUTION : The dual phase alloy for separating/refining hydrogen has a composition of, by atomic%, T100-(α+β+γ+δ)MαXβZγRδ(in the formula, T is at least one selected from the group consisting of Ti, Zr and Hf; M is at least one selected from V, Nb and Ta; X is at least one selected from the group consisting of Ag, Al, Cr, Cu, Ga, Zn and Fe; Z is at least one selected from the group consisting of B, C and P; R is at least one selected from rare earth elements including Y and La; α, β, γ and δ satisfy 15≤α≤55, 5≤β≤45, 0.1≤γ≤5 and 0≤δ≤15; and T is 5 to 60 atomic%) with inevitable impurities.
