single crystals with perfect orientation were prepared by directional solidification technology. The performance of the dual-phase single crystal (SC) can achieve 399 ppm in magnetostriction and 10.2% in tensile fracture strain

which are

respectively

28% and 5 times larger than those in single-phase Fe

SC. The slight solid solution of Tb and dispersive distributed Tb-rich particles in dual-phase SC

respectively

lead to the improvement in magnetostriction and ductility. This dual-phase SC can become the candidate for new-generation magnetostrictive materials combining significant advantages in both structural and functional properties.
