Structural Characterization of Low Carbon Foil by Asymmetrical Rolling

Abstract:

At room temperature, the low carbon steel were cold rolled from 0.5 mm to 1 μm without intermediate annealing by asymmetrical rolling (ASR) process. the microstructure were investigate by Electron Backscatter Diffraction (EBSD) and transmission electron microscopy (TEM). Lath structure (~300 nm) and local nanograins (~60nm) were obtained through ASR with extensibility up to 50,000%. The high angle boundaries were predominant. The results indicated that inhomogeneous deformation and combination deformation mechanism of dislocation slip and grain boundary slip in the foil ASR process.
