to simulate the solidification process of Sn-3.5%Pb hollow billet with the traveling magnetic field and rotating magnetic field. The effects of different kinds of flows on the temperature field... field and rotating magnetic field. Both flows can refine the grains in the hollow billet because of change of the temperature gradient and cooling rate of molten metal. The bigger the stirring velocity......
, and it can describe the magnetomechanical effect well at low external magnetic field. In the rotating bending fatigue experiments, the MMM field distribution in normal direction around cylinder specimen... fluctuates around the defect. The modified J-A model can explain experiment results well, and it is fit for MMM field characterization. Key words: metal magnetic memory; Jiles-Atherton model; rotating......
