Shear-based Deformation Processing and Characterization of Electrical Steel Sheet
Processing of electrical steel (i.e., iron-silicon) alloys containing up to 6.5wt%Si into sheet is demonstrated by application of highly confined shear deformation in the form of metal cutting. Iron-silicon (Fe-Si) alloys, of major interest to electromagnetic applications, are characterized by poor …

PRODUCTION OF NON-ORIENTED ELECTRICAL STEEL THIN STRIP SIMULATING CONDITIONS OF THE DIRECT TWIN-ROLL CASTING PROCESS
… this study, a method to cast non-oriented (NGO) electrical steel with conditions of an industrial twin roll thin strip casting (TRSC) process was investigated. A novel vacuum assisted fast cooling (VA) sampling method was developed to produce 2 mm thick strip simulating conditions of an …

Saturation Effects in 3p3L Power Transformers due to Geomagnetically Induced Currents
… four step-lap mitred joints and a high quality electrical steel. This was to closely resemble the performance of a normal power transformer. The source supply for the test circuit was carefully designed and tested to ensure that it was sufficiently robust that it would not affect the results of …
