试分析电磁场力细化晶粒的机理

The Machanism for grain refinement with electromagnetical field

本文通过对Al—4.5％Cu和Al—12.6％Si二种合金分别在固定磁场、旋转磁场,通直流电等不同条件的结晶过程研究发现;随着实验条件改变试样的晶体形貌、晶粒度差别很大.试制用电磁场理论分析了产生这种差别的理论根据.

Both A1-4.5％Cu and A1-12.6％ Si binary alloys solidified in varied conditions under the fixed electromagnetical field, the revolute electromagnetical field and the electric field. It is found that the specimens have different crystallines. Explanation to these results based on the electomagnetical theory were proposed.
