In addition.... 2) The grain refinement caused by the pulsed magnetic field is regarded as the electromagnetic vibrating forces and Joule heat effect in the melt. The pressure caused by the electromagnetic vibrating......
4.3 Magnetic pressure The calculated results for the magnetic pressure are shown in Fig.7. The direction of the magnetic pressure is approximately vertical to the centerline of the billet. The peak value of the magnetic pressure also emerges at the radial edge of the melt zone and the pressure decreases from the edge to the center. The curves of magnetic pressure of the node (the coordinate......
