Abstract
The T c, B c2, and J c were investigated for superconductors in a residual strain state for bronze processed commercial multifilamentary Nb3Sn wires. It was found that the temperature dependence of B c2 under strain obeys [1-(2/3)(πT /1.75T c)2] near T =0 and (1-T /T c) near T c. The establishment of the temperature scaling law of a global pinning force F p=J c×B was confirmed in commercial Nb3Sn wires
