应用电偶极子理论,模拟了过热合金熔体在脉冲电场作用下团簇附近电场强度分布,得出在脉冲电场及电偶极子电场耦合场强作用下,由于电迁移速度不同,致使原子团簇附近溶剂、溶质淤积,进而使小尺度团簇有可能通过重构而长大;应用静电感应原理,计算了团簇半体受力情况,得出大尺度原子团簇半体受到耦合电场力较强,团簇稳定性减弱.研究表明,熔体内原子团簇在脉冲电场作用下其尺度有均一化趋势,即某一尺度原子团簇占优。
The theory of electric dipole was used to simulate the electric field intensity distribution of the superheated alloy melt near the cluster due to the pulsed electric field. It was found that due to the different electromigration velocity due to the coupling of the electric field strength between the electric field and the electric dipole, Clusters near the solvent, solute deposition, and thus make small-scale clusters may be reconstructed by the growth; application of electrostatic induction principle, calculated half the force of the cluster, obtained large-scale atomic cluster half subjected to a strong coupling electric field , The stability of the cluster is weakened.The results show that the atomic clusters in the melt have a uniform trend in the pulsed electric field, that is, the atomic clusters of a certain scale dominate.
