摘要: 在Fe-C-P系合金熔体的凝固过程中加入脉冲电场能有效减轻晶界偏聚,改善凝固组织,同时也引起了元素的迁移和重新分布,C元素与P元素呈现出相似的迁移规律,随着电压的增加,P元素偏析标准偏差从1.67降到1.26,C元素也由1.03降到0.65. 处理后的熔体凝固组织中夹杂物主要分布在中心区域,凝固组织中未观察到含磷夹杂物,存在少量MnS和Al2O3夹杂物.

Abstract: Imposing of pulsed electric field can effectively reduce the grain boundary segregation and improve the solidification structure Fe-C-P alloy during solidification of its melt, but it can also cause the migration and redistribution of elements, in which element P migrates from the anode to the cathode, the migration law of element C is similar to P. As the voltage increases, the standard deviation of P segregation is decreased from 1.67 to 1.26, and that of C from 1.03 to 0.65. After processing, the inclusions are mainly distributed in the central region, but phosphorus-containing inclusions can not be observed, there is a small amount of MnS and Al2O3 inclusions.

Key words: pulsed electric field, solidification, migration, inclusion
