Effect of VC inhibitors in combination with unconventional dynamical heat treatment on the magnetic properties of GO steels

Abstract

The present work investigates some new approaches of grain – oriented steels processes. The suggested approach combines an application of nano – particles VC in combination with dynamic continuous annealing for secondary recrystallization in the investigated steels. Such a dynamical (fast heating) annealing and VC particles was applied to the grain – oriented steels in order to obtain abnormal grain growth with Gass crystallographic orientation development during secondary recrystallization. This abnormal gain growth led to evolution of suficienty sharp {110} Goss texture which is equal to that obtained in conventionally treated GO steels. Moreover, the steels treated by the newly method showed similar magnetic properties as the materials passed the long – time heat treated. The coercive field value of our steels reached ~ 11 A/m. This means that the proposed heat treatment in combination with VC nano – particles lead to development equal material’s quality at significantly shortened time of heat treatment in comparison to the conventional process of GO steel production.
