| Abstract: | WT5BZ]A new technique using strong pulsed magnetic field was first proposed for refining metal solidification structure .It shows that large dendritc grains can be changed into refiner and equiaxial grains by pulsed magnetic field in Al alloy solidified structure. Moreover, the stronger the pulsed magnetic filed, the much more refiner and equiaxial effects appears. This novel technique can be used in varies of metal materials and spread in industries. |
