Abstract

The magnetic field of electromagnetic stirrer was simulated by the Maxwell 2Dsoftware.The results indicate that the magnetic field lines are distributed almost around the magnetic field generator windings

and the largest magnetic induction intensity can be observed.And the reasonable current frequency is 40 Hz.The electromagnetic stirring forming apparatus for the alloy was designed on the basis of the simulated results

and the microstructure and properties of manganese alloy were investigated.The results reveal that the electromagnetic stirring technique can improve the microstructure of manganese alloy.By observing crack number in the alloy at different cooling time and cooling rate

the microstructure and properties of the Mn alloy exhibit desirable with cooling at a third-quarter natural cooling time.
