Abstract:

The mechanical properties of filamentary Nb3Sn superconducting composites have been investigated. The effect of reaction conditions and variation of component dimensions on the strain which can be accommodated before loss of current carrying capacity occurs has been determined, Critical strains to failure lie within the range 1-3%. The failure mechanism of Nb3Sn layers is discussed in terms of the fracture mechanics of composite materials. Commercial types of composite consisting, typically, of 1500 filaments in bronze were found to withstand repeated stressing to 3.6 × 108Nm-2in liquid helium without degradation of superconductivity.
