(abstract)

Large-scale devices, such as the next generation high energy particle accelerator project, demand the enhancement of the Jc and cost performance of Nb3Sn wires. The cost performance is closely related to the design and drawability of the wires. This study aims to increase the hardness of the soft Sn core of the wires through the precipitation of fine compound particles, improve the hardness balance between the constituent materials (Nb, Cu, and Sn), and investigate the feasibility of this method for practical wire drawing. By choosing an appropriate content ratio for Cu and Zn, Sn can contain 50at% Cu–Zn and exhibit ductility. The hardness of Sn could be increased by a factor of approximately 3
