Abstract

The chemically patterned austenite with alternately distributed Mn-rich and Mn-poor regions is introduced via fast-heating on initial pearlite microstructure in a Fe–0.6C–2.3Mn–1.7Si steel. The bainitic transformation kinetics is accelerated transformed from chemically patterned austenite compared with chemically homogeneous austenite, which can be attributed to the increased driving force and reduced nucleation activation energy for bainite formation in the Mn-poor regions, as well as the more fluent carbon diffusion path caused by chemical patterning.
