Research status and prospects of melt refining and purification technology of magnesium alloys

Refining and purification is a significant way to obtain pure and high-quality magnesium alloy melts. This paper summarizes the flux refining methods and non-flux purification methods (blowing purification, filtration purification, electromagnetic purification and ultrasonic purification). It also introduces the composite refining technologies that have been widely researched and applied in recent years, including low-voltage pulse...
