| Outline of Final Research Achievements |
Fabrication of (Zr,Ti)-Nb based nanocrystal alloys were performed. The (Zr,Ti)-Nb based nanocrystal alloys were fabricated by annealing of (Zr,Ti)-Nb based precursors, which were prepared using rapid quench technique. For preparing of the precursor, the Zr-Nb-Al-Co and Zr-Nb-Al-Co-Ti superconducting precursors with nanoparticles dispersed in amorphous matrix were obtained. The Zr-Nb-Al-Co-Ti nanocrystalline alloys with full nanocrystal structure were fabricated by annealing of the precursor. The Zr55Nb15Al15Co9Ti6 nanocrystal alloys exhibited superconductivity blow approximately 5K. The Tc of Zr55Nb20Al15Co10 superconducting nanocrystal alloy was approximately 8K.
