Effect of nitriding on grain oriented silicon steel bearing aluminum

Abstract

All high permeability GO is manufactured using AIN as the main inhibitor. Two types of inhibitor preparation of GO have been realized industrially, i.e., extra high and extra low slab reheating temperature methods. Therefore, from a purely metallurgical viewpoint, the possibility of a middle temperature slab reheating method was examined and the effect of nitriding was investigated. Metallurgically, this method is located between the Extra high and Extra low temperature methods. Furthermore, it is essential that a suitable combination of inhibitor intensity and primary diameter, controlled by nitriding and heat treatments respectively can provide sharp Goss orientation. © 2005 ISIJ.
