Influence of New System Nano-Inhibitors on the Abnormal Grain Growth with Goss Crystallographic Orientation of Silicon Steels

Article Preview

Abstract:

In the present work some new approaches have proposed for the grain oriented steel fabrication. This approach employs the new system of VC nanoprecipitates in the combination with dynamic continuous annealing for secondary recrystallization. The new system of VC inhibitors and dynamic annealing was applied to the grain oriented steel in order to obtain abnormal grain growth with Goss crystallographic orientation and considerably reduces the preparation time as the whole process lasts only several minutes. The EBSD analysis shown that suggested procedure led to evolution of the sufficiently strong {110}<001> Goss texture, which is comparable to that obtained in the conventionally treated GO steels. Moreover, the steels treated by this new method have the comparable final magnetic properties as the materials passed the conventional long – time heat treatment.
