Co-deformation and possible fracture during the drawing of internal tin multifilamentary superconductor wires was investigated by FEM simulation. A thermomechanical, elasto-plastic finite-element ...

This paper is concerned with the hydrostatic extrusion of mono-core, bronze-process superconductor billets. The thermo-mechanical, elasto-plastic finite-element method is used to analyze the extrusion ...

Bulk rhombohedral Bi at ambient pressure is a well-known semimetal, and its transition to a superconductor has not been observed, at least down to 50 mK. We report that, unlike bulk rhombohedral Bi, ...
