HYDROGEN SEPARATION ALLOY, RAW MATERIAL FOR FORMING THE HYDROGEN SEPARATION ALLOY THROUGH ROLLING, METHOD FOR MANUFACTURING HYDROGEN SEPARATION ALLOY, AND HYDROGEN SEPARATOR

摘要

PPROBLEM TO BE SOLVED: To provide a hydrogen separation alloy, drastically increase hydrogen embrittlement resistance while retaining a high hydrogen permeability coefficient, a raw material for forming the hydrogen separation alloy through rolling to which rolling is applied, a method for manufacturing the hydrogen separation alloy, and a hydrogen separator. PSOLUTION: The hydrogen separation alloy is composed of an alloy having a composition comprising, by atom%, TSB100-(++)/SBMSB/SBXSB/SBZSB/SB(wherein element T is at least one chosen from the group consisting of V, Nb and Ta; element M is at least one chosen from the group consisting of Ti, Zr and Hf; element X is at least one chosen from the group consisting of Co and Ni; element Z is at least one chosen from the group consisting of B, C and P; and , and satisfy the relations: 545, 1555 and 0.15, respectively, and the sum of ++ is within the range of 20-80) and unavoidable impurities.
