电磁复合场对Zn-10wt%Bi过偏晶合金凝固组织的影响
The effect of electromagnetic compound field on the solidified microstructure of Zn-lO wt% Bi hyper-monotectic alloy
摘要
Abstract
The effects of different electro-magnetic body forces on the microstructure and solidifying process of Zn-10 wt%Bi hyper- monotectic alloy under the condition of high magnetic field are investigated in this paper. The result indicate, on the one hand, that the solidified structure is wanted most and the diameter of the second phase particle is minimum when the alternative current (50 Hz) increases to a certain value. On the other hand, the degree of segregation, dispersion and size of the second Bi phase particles in solidi- fied structure of Zn-10 wt%Bi hyper-monotectic alloy are refined significantly with the increase of magnetic induction intensity under a fixed alternative current (50 Hz) value. The analysis result indicates that both the magnetic induction intensity and alternative current intensity have a significant effect on solidified structure so that we can obtain a more competitive solidified structure of monotectic alloy by controlling the intensity of magnetic induction and alternative current.关键词
