摘要：
The dispersion behavior of SiC particles in molten Mg alloys during stirring casting using four-bladed stirrer was investigated by numerical simulation. The effects of stirring speeds (300, 500, 800 rpm) and stirring temperatures (590, 620, 640 degrees C) on the dispersion uniformity of the SiC particles were investigated. Simulation results show that the particle concentration fluctuates along both the height and radial directions of the stirred vessel to varying degrees. When the stirring casting was performed at 590 degrees C and at 300 rpm, a relatively uniform spatial distribution of SiC particles without large aggregations was obtained.
