Abstract

Abstract Fe–6.5 wt.%Si high silicon steel wires with a diameter of 1.6 mm are fabricated successfully by hot drawing. The high silicon steel wires show much better ductility than sheets. The tensile strength and elongation of the wires at the room temperature can reach 1.31 GPa and 1.4%, respectively. The tensile strength and elongation of the rolling sheet at the room temperature are 0.8 GPa and 0, respectively. The microstructure analyses show that the elongated grains after drawing and reduced ordering phases by deformation in the wires might contribute to its good ductility. Bs value of 1.437 T and Hc value of 16.96 A/m are obtained for the wire after proper heat treatment for the wires.
