Abstract

Internal lattice strains under a tensile load for a seven-strand cable consisting of three pre-bent CuNb/Nb ₃Sn and four stainless steel strands were measured by neutron diffraction at room temperature in order to investigate the improvement of mechanical properties of Nb ₃Sn strands. Stresslattice strain curves of Nb ₃Sn and stainless steel strands were obtained, and the effective stress for a Nb ₃Sn strand was estimated by considering the load sharing of a stainless strand. It was found that the reinforcement with stainless steel strands is an effective way to reduce an applied electromagnetic tensile load for Nb ₃Sn strands for superconducting magnet application.
