| Abstract: | The discovery and current advances of intragranular ferrite and its relation with microstructure control are reviewed. The nucleation mechanisms and factors affecting the formation of intragranular ferrite are briefly introduced. Three-dimensional morphology and growth kinetics of intragranular ferrite are discussed. Finally, the important role and effect of intragranular ferrite on the microstructure refinement were analyzed for low carbon microalloyed steels from the view point of nucleation, growth, morphology and distribution. |
