主　　题：ZL101 aluminum alloy semi-solid slurry serpentine channel 

摘      要：Semi-solid slurry of ZL101 aluminum alloy was prepared using serpentine channel. The influences of the pouring temperature, the number of curves and the serpentine channel temperature on the microstructure of semi-solid ZL101 aluminum alloy were investigated. The results show that, satisfied semi-solid slurry of ZL101 aluminum alloy was prepared with pouring at 630-680℃. The morphology of primaryα（Al） grains transforms from rosette to spheroid with the decrease of pouring temperature. At the same pouring temperature, increasing the number of curves can improve the morphology of primaryα（Al） grains and decrease the grain size. Qualified slurry can be attained with lowering the pouring temperature when the serpentine channel temperature is higher. The alloy melt has the effect of“self-stirringin the serpentine channel, which can make the primary nuclei gradually evolve into spherical and near-spherical grains.
