Relationship between Grain Boundary Diffusion and Ferrite Grain Size Formed through Dynamic Recrystallization during Large Strain Deformation

Abstract:

Article Preview

During large strain deformation of materials, the high angle grain boundary spacing approaches the order of mean thermal diffusion distances for given deformation conditions. Based on the results of microstructural and grain size analysis in low carbon steel subjected to large strain-high Z deformation, the evolved ferrite grain size was found to be controlled by the Zener-Hollomon parameter and grain boundary diffusion was found to be the controlling mechanism.
