Abstract

Fe-6.5wt%Si alloy has excellent soft magnetic properties, but it is hard to be cold-rolled due to appearance of ordered phases in this alloy. In this paper we report that ultra thin Fe-6.5wt%Si sheet of 0.05 mm thick was obtained by heavily cold rolling. By means of optical microscope, micro-hardness indenter, instron, SEM and X-ray diffraction, the effect of heat treatment on mechanical properties of this alloy sheet was investigated. The heavily cold-rolled sheet exhibits some extent of ductility. The ultimate tensile strength reaches 1.93 GPa. After heat treatment, micro-hardness is decreased and the ductility is lost, especially at temperature above 650°C when recrystallization takes place. The reason for decreasing the ductility lies in the ordered DO ₃ phase transformation.
