Effects of Rotating Electromagnetic Field on Solidification Microstructure of ZA27 Alloy
In the present, by using rotating electromagnetic field (REMF) equipment, the effects of REMF for crystal growth processes in cast ZA27 alloy were investigated. It was found that the growth of the primary and secondary dendrites was restrained by alternative REMF and solidification microstructure transformed from dendrite to non-dendrite and globular crystal. The grain refinement effects were further improved with increasing of voltage.
