Mechanical properties of Nb/sub 3/Sn stranded superconducting potted cable windings
The electromagnetic stresses in projected designs of high-field magnet coils sometimes exceed the yield points or creep strengths of the presently used coil-winding materials. This is especially true of react-after-winding Nb/sub 3/Sn coils, plastic insulating materials, and the crossed strands of twisted cable. This report presents compression stress-strain curves of stranded and twisted-flat-cable coil-winding specimens for reacted and epoxy-impregnated Nb/sub 3/Sn coils, at 300/sup 0/K and 80/sup 0/K. The lateral and longitudinal strains of one specimen were meaured along with the direct compressive stress-strain, at 300/sup 0/K. A similar specimen was compressed to 40 MPa (6 kpsi) at room temperature and then to 145 MPa (20 kpsi) at 80/sup 0/K. Plastic flow occurred up the maximum stress. Stress cycles subsequent to maximum stress were elastic. Some specimens were mounted in a rigid enclosure to simulate hydrostatic containment of the magnet coil. Pure annealed Cu was tested at 300/sup 0/K, and pure epoxy was tested at 300 and 80/sup 0/K. In addition the thermal contractions from 300 to 80/sup 0/K were measured.
