Abstract
In this research, super gravity field was introduced in the solidification process of high carbon steelHigh-carbon steel . The experimental results show that the solidification structureSolidification structure of Fe–1 wt% C steel can be largely refined by applying super gravitySuper gravity at the cooling rate of 10 °C/min. Both the primary and secondary dendrite length was markedly reduced. In addition, the eutectic structure in the inter-dendrite was also refined with the obvious reduce of eutectic space. However, the macro-segregation of C along the direction of super gravity was caused with higher weight percent at the upper area than that at the bottom of the sample. The mechanism of solidification structure refinement and the C macro-segregation of Fe–1 wt% C steel in super gravity field were also discussed in this paper.
