Abstract

Different initial texture of ring rolled AA2014 alloy was processed to one pass in Equal channel angular extrusion (ECAE) at room temperature. The material flow/deformation characteristics as well as the degree of grain refinement, as a function of different initial grain morphological orientation, vis-sa-vis grain orientation, are studied. Macroscopic and microscopic investigation by Optical microscope (OM) confirms the significant variation in the shearing characteristics of grains in the billets in each orientation. OM observations also suggested that the severity of deformation was more in middle portions of the extruded billets. TEM observations made on the samples also confirmed the existence of regions which had undergone the different degree of dynamic recovery and recrystallisation after passing through shear deformation zone. © (2012) Trans Tech Publications, Switzerland.
