本文进行了强静磁场下电磁振荡对Al-4.5%Cu合金凝固组织影响的研究，发现同时施加静磁场和交变电流后，初生-Al相由粗大的树枝晶转变成细小的球状晶，晶粒的细化程度随电流的增大而增加，随磁场增加先增加后略有降低。X射线衍射结果表明，施加磁场后，晶粒的<111>晶向沿磁场方向取向。晶粒取...

金属学报(英文版) doi:10.1016/S1006-7191(08)60068-X

The effects of electromagnetic vibration on the grain refinement in directional solidification were investigated. It was found that the electromagnetic vibration applied in the melt not only can refine grains remarkably but also can enhance both tensile strength and ductility values of Al-6%Si alloy...

An electromagnetic vibration was generated by simultaneously imposing a strong static magnetic field (up to 10　T) and an alternative electricity current to the metal. Its effects on the solidification structure of eutectic Al-Si alloy have been investigated experimentally. It is found that the eutec...
