Abstract
The uniaxial strain dependence of the critical current was measured both in tension and compression in Bi-2212 high-temperature superconducting round wires. We observed that permanent damage to the critical current can easily occur due to strain. To improve the electro-mechanical properties of Bi-2212 wires, development of stronger sheathing materials is needed. Ideal materials would be not only mechanically strong, but also chemically compatible with Bi-2212 during the final heat treatment. To identify such materials, we measured stress-strain properties of some new Ag alloys and extracted their respective Youngs modulus and yield strength. The database generated may be useful to develop new Bi-2212 strands for fabricating high-field superconducting magnets above 20 Tesla.Citation
