Summary

It was predicted and experimentally verified that the upper-critical magnetic field and critical current can be improved by the preloading treatment through the control of the residual strain of niobium-tin. It was shown for one sample with a lenght of 300 m that the prestress level on the composites, at which the critical current is reduced due to the breakage of niobium-tin, would be reduced by 20% in comparison with that for short samples of 25 mm.
