Effects of electromagnetic field on aluminum alloys liquid–solid continuous rheological structure evolution

By applying a special combined magnetic field (MF) to the molten aluminum solidification–deformation process, we obtain roll-casting aluminum strips under different electromagnetic field (EMF). Analyses of these strips show that EMF causes pronounced changes in aluminum roll-casting strip’s structure, and has significant effects on mechanical properties of finished sheets and plates thereof. With rational EMF parameters, breakthroughs can be achieved in the roll-casting strip finishing processing.
