Stress effects in a Nb3Sn conductor proposed for use in the magnetic fusion energy program

Because of significant interest in multifilamentary Nb3Sn conductors with copper stabilization for large magnetic devices, knowledge of stress effects on electrical and mechanical properties of such conductors is important. The conductor studied in this experiment is proposed for use as a basic strand material to form a force-cooled cable for the Large Coil Program at ORNL. Stress-strain curves and stress effects on the critical current of differently reacted conductors are presented
