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

Nb 3Sn superconducting wires made with restacked-rod process (RRP®) were found to have a dramatically improved resilience to axial tensile strain when alloyed with Ti as compared to Ta. Whereas Ta-alloyed Nb 3Sn in RRP wires showed permanent damage to its
