Notes:
Interstitial-free steel sheets have been processed using a novel severe plastic deformationtechnique - continuous frictional angular extrusion (CFAE), in order to produce ultrafine grainedstructures. The deformation was carried out at room temperature and individual sheet specimens wererepeatedly processed to various passes. An overall grain size of 200nm was achieved after 8 passes (oran equivalent total strain of 5.3). The present paper reports the evolution of microstructures duringdeformation, which were examined and characterized using electron backscatter imaging and highresolution EBSD in a field emission gun SEM. The mechanisms of grain refinement are discussed
