Type of article: Article

Summary

RECENT DEVELOPMENTS IN THE FABRICATION TECHNIQUES OF IN-SITU PROCESSED MULTIFILAMENTARY NIOBIUM-TIN CONDUCTORS ARE REVIEWED. THIS PROCESS IS ONE OF POSSIBLE METHODS WHICH CAN BE USED TO MINIMIZE THE PROBLEMS ASSOCIATED WITH THE BRONZE PROCESS. IN THIS PAPER THE MELTING AND CASTING TECHNIQUES OF COPPER-NIOBIUM INGOT AND ITS TRANSFORMATION INTO MULTIFILAMENTARY NIOBIUM-TIN CONDUCTORS ARE DISCUSSED IN TERMS OF THE MORPHOLOGY AND DRAWABILITY OF THE INGOTS. IN ADDITION, THE CHARACTERISTIC FEATURES OF SUPERCONDUCTING PROPERTIES OF THE IN-SITU PROCESSED CONDUCTORS ARE PRESENTED WITH EVIDENCE OF A STRONG DEPENDENCE OF THE SUPERCONDUCTING CRITICAL CURRENT, FLUX-PINNING AND ELECTROMAGNETIC COUPLING ON THE MICROGEOMETRY IN THE CONDUCTORS.
