Extruded microstructure of Zn–5 wt-%Al eutectic alloy processed by twin screw extrusion
2012
Materials Science and Technology
Semisolid extrusion with twin screw extruder has been successfully developed for eutectic alloy. In this process, the eutectic melt is sheared and cooled down inside the twin screw extruder to a semisolid state and simultaneously extruded through an open die at a temperature close to solidus. The accurate control of heat balance in the extruder results in the formation of two solid phases and one liquid phase in the Zn-5 wt-%Al eutectic alloy.
