Core loss reduction in electrical steels through materials processing

AN INVESTIGATION TO BAINITE FORMATION MORPHOLOGIES IN NI-CR BEARING LOW CARBON STEELS THROUGH THERMOMECHANICAL PROCESSING

The presence of bainite in the microstructure of steels to obtain a proper combination of strength and toughness has always been desired. The previous works however have shown that the presence of preferred bainite morphologies in the microstructure of any steel would not be readily accessible. In addition, the appearance of different bainite morphologies in the microstructure of any steel is d...

Core loss models in electrical steel sheets with different orientation

Classical core loss models such as two components model or modified Steinmetz model are still popular and used by engineers to loss prediction in electrical machines. They may carry to increase discrepancy between calculated and measured values. This discrepancy increases with grain-orientation and with increasing discrepancy from sinusoidal magnetisation conditions. Statistical loss model show...

Advances in Core Loss Calculations for Magnetic Materials

Effect of Cold Rolling sequence on the Texture Development and Magnetic Loss of Grain Oriented Electrical Steels

Electrical steels are important alloys widely used in electrical instruments. The magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of Goss texture ({110} ).The direction of is the softest direction for magnetism.  In this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...
