Abstract:

The properties of hot rolled Fe-۶.۵ wt.% Si alloy sheets with rapid cooling methods including water-quenching and oil-quenching were investigated. Effects of using these rapid cooling methods after Fe-۶.۵ wt% Si hot rolled on microstructural, ordered phases, microhardness and magnetic characterization, using by optical microscopy (OM), X-ray diffraction (XRD), vickerss microhardness test and magnetometric analysis of vibrating specimens (VSM ), were studied respectively. The results show that the deformation mechanisms in hot rolling sheets with rapid cooling is dynamic recrystallization It was also found that quenching in water compared to quenching in oil after hot-rolling Fe-۶.۵ wt. %Si alloy could completely suppress the D۰۳ ordering phase and greatly reduce the intensity of the B۲ ordering phase. The minimum microhardness(۲۱۶ Hv) was obtained from hot-rolled sheet quenched in water. While the quenched sheet in oil showed high microhardness(۳۷۱ Hv). In measurement the magnetic properties , coercivity force Was obtained for specimens quenched in water and oil ,۱۷۵ and ۱۴۳ A/m respectively. While the amount of saturation magnetization of both specimens was close to each other(≅۱.۹ T). Therefore, from the results obtained in this study, it can be stated that quenching in water of Fe - ۶.۵ wt% Si alloy after hot rolling compared to quenching in oil can improve the workability alloy for the next stages of deformation in hot and cold rolling.
