Summary

The current-carrying capacity of multifilamentary niobium-tin wires under transverse, compressive stress was investigated. The recorded voltage-current curves have been studied in detail. It was observed that transverse stress does not only cause a reduction of the maximum current, but also leads to drastic changes in the shape of the voltage-current curve. If stress is applied, the n-value is large for currents beyond the 1.E(-14) ohm.meter criterion. For lower currents, n-values drop to much lower values. As a consequence, significant voltages were already found at about 60% of the original critical current for a stress of 100 megapascals.
