It is well established that the extended range V(I) transition behavior in
filamentary superconducting composites depends strongly on the processing
conditions of the composite. Based on previous work, a model proposed by
Warnes et al predicts that the second derivative of the V(I) transition is related to
a more fundamental...
Mechanical properties of Nb-Ti composite superconducting wires were tested at
room temperature. The results were analysed using simple composite theory, the rule
of mixtures. The objective is to predict the mechanical properties of Nb-Ti
superconducting composite wires as a function of volume ratio and geometry of the
components, the composite...
The metallurgy and superconductivity of the Nb-Ti-Ta ternary alloy system were studied. The Nb-Ti, and Ta-Ti binary samples, and Nb-Ti-Ta ternary samples were precipitation heat treated under different schedules. After the precipitating heat treatment, the samples were characterized by X-Ray Diffraction (XRD) techniques. Equilibrium binary and ternary phase diagrams based...
