The melt spinning of Pb–Bi system alloy with Pyrex glass was investigated as a means of producing a superconducting long filament with high Tc.
A Pb80Bi20 filament with maximum Tc of 11.0 K was obtained from the molten state at 1500 K with a spinning speed of 0.95 m·s−1. The filament was 43×10−6 m in diameter and a ductile material with tensile strength of 50 MPa and elongation of 2.9%. The filament consisted of fine crystal grains with grain size of 1000×10−10 m, and its structure was metastable and a mixture of fcc with ⟨111⟩ fiber texture and hcp.
