Effect of Electromagnetic Stirring Parameters on Microstructure of Semi-solid ZL104 Alloy

The effect of stirring frequency and stirring power on the microstructure of semi-solid ZL104 alloy was studied by EMS-SM05 type electromagnetic stirrer. The results show that under the experiment condition,when the stirring frequency is higher than 40 Hz,the semi-solid ZL104 alloy's microstructure is ideal,and with the increase of the stirring power,primaryα-Al phase increases in the number and becomes more round and finer. When the stirring power is higher than 7735 W,the globular primary phase α-Al's morphology and size does not make much difference,so it is the best stirring power.
