Effect of strip-cast micro-segregation on phase transformations in medium to high-carbon steels

The solidification of strip-cast alloys resulted in chemical heterogeneities known as micro-segregation, which were found to significantly impact phase transformations in nano-bainitic steels. The presence of micro-segregation resulted in an increase in the kinetics of isothermal nano-bainite formation, and a competitive transformation between bainite and pearlite during continuous cooling.
