Application Research on Annular Electromagnetic Stirring Casting Process of Al-Zn-Mg-Cu Alloy

Abstract:

Annular electromagnetic stirring (A-EMS) process is verified an advanced metal melt treatment technology. Application research was performed to investigate the solidification behavior of Al-Zn-Mg-Cu alloy in this study. The results indicated that uniformly fine microstructure, less composition macro-segregation and improved mechanical properties were achieved.
