Microstructure and texture of interstitial-free steel fabricated by continuous frictional angular extrusion
Continuous frictional angular extrusion (CFAE)is a new method of severe plastic deformation,which takes advantages of rolling and equal channel angular extrusion (ECAE)and gives an exciting idea for producing ultra-fine grained metals and alloys.The deformation was carried out at room temperature and individual sheet specimens were repeatedly processed to various passes.An overall grain size of 200nm was achieved after 8 passes.The present paper discussed the properties of microstructures and textures during the process of deformation,which were analyzed by high resolution EBSD,X-ray diffraction (XRD)and hardness testing.
