The Influences of Reheating Process to the Semi-Solid Microstructure of Hypereutectic Al-22Si-1.93Fe-1.36Mn Alloy by Cooling Slope

Abstract:

The microstructures of hypereutectic Al-22Si-1.93Fe-1.36Mn alloys were improved by cooling slope (CS) that carried out using segmented cooling plates. Then the hypereutectic Al-22Si-1.93Fe-1.36Mn alloy casted by CS is reheated in its semi-solid interval for different holding time, respectively. The aim is to get the microstructure evolution law of reheating hypereutectic Al-Si alloys after adding Fe and Mn. Based on the microstructures characteristics of alloy with different holding time, the evolution law of alloy microstructure in reheating process is obtained.
