A new approach for segregation control in alloys by high magnetic field gradients and its application in functional materials
In this study,the effects of high magnetic field gradients on the segregation of alloying elements,crystallized phases,and particles in alloys during solidification process and corresponding microstructures were discussed.It was confirmed that applying an external high magnetic field gradient during solidification process is an effective processing route for controlling segregation in alloys and then fabricating functional materials which have special microstructures and properties.Such controlling and fabrication were realized by controlling the migration of the alloying elements,crystallized phases,and particles in the liquid matrix on the basis of the Lorentz and magnetic forces.
