Investigation of Semi-Solid Slurries Prepared by Helical Curve Duct

Abstract:

A new method of helical curve duct (HCD) to prepare semi-solid slurry was investigated. The semi-solid slurry of A356, AZ91, Cu-2.21wt%Ca (0.45wt%Ce) alloys were prepared through this method of HCD. Comparison of the microstructures of slurry prepared through the helical curve duct with different structure parameters and process parameters are made and the effects of structure and process parameters on microstructures are analyzed. The results show that the melt is stirred effectively by flowing through the helical curve duct and the semi-solid slurry of alloys could be prepared through the helical curve duct process; Spherical microstructures of alloy slurry were obtained through controlling or adjusting the process parameters to control solidification conditions.
