Super gravity was introduced in the solidification process of high carbon steel. The experiment results show that the solidification structure can be refined by applying super gravity at the cooling rate of 10 °C/min. Obviously, both the primary and secondary dendrite length was greatly reduced. In addition, the eutectic structure in the interdendritic tends to be spheroidized and refined. However, the macro-segregation of C along the direction of super gravity was caused with higher wt percent at the upper area than that at the bottom of the sample. The mechanism of solidification structure refinement and the C macro-segregation in super gravity field were also discussed in this paper.
