Effect of melt pulse electric current and thermal treatment on A356 alloy
摘要
Effects of the melt pulse electric current and thermal treatment on solidification structures of A356 alloywere investigated. In the experiments, the low temperature melt(953 K and 903 K) treated by pulse electric currentwas mixed with high temperature melt(1 223 K). By the control experiments, the results show that the solidificationstructure of A356 alloy is refined apparently by the pulse electric current togeth er with melt thermal treatmentprocess, and the mechanical properties, especially the elongation ratio of the specimen treated is improved greatly.The structure change of the melt by pulse electric current and melt thermal treatment is the main reason for the re-finement of the solidification structure of A356 alloy.
