摘要: Abstract Effect of uniaxial tensile and compressive stresses on critical temperatures T cm (midpoint the transition curve) superconducting composites (in situ formed Cu–Nb, Cu–NbTi bronze–Nb 3 Sn industrial wires were studied. Results obtained for Cu–Nb are qualitatively similar to those composite resistive field H r , presented in first part this paper. Again, average derivative d /d σ (as well as its ) exceeds respective value pure Nb by about an order magnitude. This other results study discussed.
