In order to investigate the effects of heating rate on the reverted austenite structure,the microstructures after partial or complete reversion was studied by thermal dilatometer and Electron backscatter diffraction (EBSD). It was found that high heating rate promotes the formation of globular austenite,while low heating rate favors the formation of acicular austenite. Meanwhile,higher heating rate leads to finer austenite structures after reversion. High heating rate makes the nucleation and growth of the reverted austenite occurred at high temperatures,at which the growth of the globular austenite is substitutional alloying elements partitioning-less and grows very fast. Therefore,high heating rate enhances the formation of globular austenite.
