A new fabrication process of Fe-based ribbon with creep-induced anisotropy

Abstract Continuous stress-annealing process (CSA), in which a ribbon under tensile stress passes through a furnace, was carried out for obtaining long Fe–Cu–Nb–Si–B ribbons with creep-induced anisotropy. It was clarified that the creep-induced anisotropy Kuc is almost the same in magnitude for the moving velocity vm range of 1–100 cm/min at the annealing temperature of 530 °C, which suggests that a remarkable reduction in annealing time can be achieved. Furthermore, an increase in annealing temperature enabled us to increase vm up to 275 cm/min. Thus, CSA is an attractive method for applying ribbons with creep-induced anisotropy to mass production.
