Paper Title:
Formation of Non-Dendritic Microstructure of Semi-Solid Magnesium Alloy by Introducing Gas Bubbles
  Abstract

A new technique of introducing gas bubbles during isothermal period of AZ31 magnesium to prepare semi-solid slurry has been reported. The effect of resting time after stirring on the microstructure of the slurry is discussed. Results show that the dendrites and liquid phase reduced, the non-dendritic grains grew up and became spheroidized. A fully grain-refined structure can be obtained with 60s resting time.
