摘要：

The mechanical properties of in situ Cu-36 wt% Nb-x wt% Sn superconducting wires are presented where 5<x<20 wt% Sn. For high x, no degradation of critical current Jc is observed for stresses σ up to 700 MPa (∼100 ksi) and a maximum Jc occurs at σ≃450 MPa. Strains of ∼0.6-0.9% are measured at 300 and 77 K for 450 MPa, and ∼1.5-2% for 700 MPa. Cyclic stress data are consistent with a prestress model for composite materials.
