Influence of Electromagnetic Stirring Parameters and Isothermal Extruding on Semi-Solid Forming Performance of ZA27 Alloys

Abstract:

In this paper, the methods of electromagnetic stirring and isothermal extruding were used to study the semi-solid forming performance of ZA27 alloys. Through summarizing and analyzing the stirring experimental results, the reasonable parameter combination of electromagnetic stirring is that inputting voltage is 180V-200V and stopping stirring temperature is 465°C-475°C and cooling method is quenching. After ZA27 alloys are stirred by using above parameter combination,the spherical microstructures are obtained.Then the billets which were prepared by using above reasonable parameter combination were reheated to semi-solid temperature range for isothermal extruding.The extruding ratio was 4.Because the recrystallization occurs during extruding,the grains of ZA27 alloys become smaller and more uniform after isothermal extruding and per unit extruding force of semi-solid ZA27 alloys decreases by 1/4-1/5 times than that of general casting ZA27 alloys.These results provide a reliable experimental basis for production and application of ZA27 alloys.
