摘要：
The A356 aluminum alloy semi-solid slurry by damper cooling tube method was prepared under different pouring temperature conditions, and was compared with ones by cooling slope method. The results show that with decreasing in pouring temperature, the grain size and shape factors become smaller and smaller, which means the spheroidization of grain is higher and higher. Compared with ones by cooling slope method, the grain in the semi-solid slurry exhibits finer and more roundness by damper cooling tube in the conditions of the same processing parameters.
