in this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-orientedelectrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °cfor 35 seconds. finally, all of them were fully...

The core loss of electrical steel is defined as the dissipation of electrical energy in the form of heat during magnetization by an alternating current. Many efforts have been made to reduce the core loss. Numerous parameters, including the chemical composition and the metallurgical technology, influence the properties of the steel. Electrical steel sheets are mainly produced from Fe-Si-C alloy...

Electrical steels are undoubtedly the most important soft magnetic materials in use today. Applications vary in quantities from the few ounces used in small relays or pulse transformers to tons used in generators, motors, and transformers. There are two principal types of electrical steels: grain oriented and non-oriented steels. The grain oriented (GO) electrotechnical steel sheets are widely ...

The effect of additions of antimony (0.05% Sb) to silicon steel on the improvement of the electrical properties of non-oriented steel sheet was investigated. Measurements of surface segregation of Sb were performed under UHV conditions in the temperature range from 450 to 900 OC, using AES and TDS. Maximum equilibrium surface segregation of antimony was determined at 700 OC. At higher temperatu...
