摘要
New fabrication techniques have been developed to produce a homogeneous array of very long-very thin filaments of Nb3Sn in a Cu matrix. With the use of chill casting and drawing techniques one can produce a superconducting composite wire 0.025 cm in diameter which has approximately 500,000 Nb3Sn filaments uniformly distributed across the cross section8 Typically the filaments have a ribbon shape about 200A thick and 4000Å wide. Critical currents based on the total area are greater than 106 A/cm2 in zero field and greater than 104 A/cm2 at 14 Tesla so the performance compares favorably with commercial tape or commercial multi-filamentary wire. Special features of the material are the ease of fabrication, the low reaction temperatures (500°C), strain tolerance, and the strength of the material. © 1979 IEEE
