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.
In this paper, Al-4.5% Cu and Al-12.6% Si two alloys were found in the fixed magnetic field, rotating magnetic field, through the DC current and other different conditions of the crystallization process found; with the experimental conditions to change the sample’s crystal morphology, The degree of difference is very large.Piloting electromagnetic field theory to analyze the theoretical basis to produce this difference.
