Outline of Final Research Achievements

We have developed a high mechanical strength Nb3Sn multifilamentary wire that can withstand huge thermal and mechanical stress and strain in response to the design requirements for "high current and high electromagnetic force" of the superconducting magnets for a DEMO applications. We proposed a high mechanical strength bronze processed Nb3Sn wire with a new concept called "internal matrix strengthening (solid solution strengthening) based on phase transformation theory of Cu system binary alloy". We developed to the new Cu-Sn-In and Cu-Sn-Zn ternary alloys as bronze matrix materials, and demonstrated the internal matrix strength Nb3Sn multifilamentary wire using ternary bronze alloy matrix.
The tensile stress/strain dependence on the critical current property of the internal matrix strength Nb3Sn wires was improved compared to the CuNb alloy reinforced wire. We proved a new possibility of high strength Nb3Sn wire using internal matrix strengthening (solid solution strengthening).

Academic Significance and Societal Importance of the Research Achievements

世界的に見ても例がない線材構成である三元系ブロンズ合金を用いた内部マトリックス補強Nb3Sn線材を実験的に示し、新しい高強度Nb3Sn線材を実証した。この内部マトリックス強化は、Nb3Sn線材の最大の弱点である機械特性の改善に対して直接的に寄与する手法であり、高磁場・高電磁力が想定される核融合原型炉への適用も可能な新しいNb3Sn線材と考えられ、大変意義深い成果が得られた。
また、本研究成果は、核融合工学の進展だけでなく、高強度Nb3Sn線材を要する超大型強磁場マグネットを必要する大型加速器科学や重粒子線医療にも大きく貢献する可能性がある。
