Type of article: Article

Summary

THE NIOBIUM-TIN LAYER IN THE COMPOSITE WIRE IS COMPRESSIVELY PRESTRAINED AT CRYOGENIC TEMPERATURES. THIS RESULTANT COMPRESSIVE PRESTRAIN AFFECTS SUPERCONDUCTING PROPERTIES AND THE MARTENSITIC TRANSFORMATION OF THE BRONZE-PROCESSED NIOBIUM-TIN COMPOUNDS. MARTENSITIC TRANSFORMATION IS INEVITABLE FOR THE PURE NIOBIUM-TIN COMPOUND AT AND NEAR THE STOICHIOMETRIC COMPOSITION, AND THIS TRANSFORMATION BRINGS ABOUT A DECREASE IN THE UPPER CRITICAL FIELD OF NIOBIUM-TIN.
