摘要：

Cu-V3Ga composites were prepared from in situ formed multifilamentary Cu-V wires containing 20 vol.% of vanadium filaments. The highest value of the upper critical field at 4.2 K of the reacted composites was found to be 22.4 T, with a corresponding midpoint superconducting transition of 15.5 K. The overall critical-current density compares favorably with commercial V3Ga composites over the entire field range (2×105 A/cm2 at 4 T, 104 A/cm2 at 18 T).
