Evolution of Microstructure and Crystallographic Texture in AA2014 Aluminium Alloy during Equal Channel Angular Extrusion

摘要

Present work addresses the evolution of texture and microstructure of equal channel angular extrusion (ECAE) processed AA2014 Al alloy upto four passes at room temperature by adopting route B_C. TEM is used to assess the microstructural changes during each ECAE pass. Texture measurements on samples of each pass were carried out by XRD technique. The evolution of texture components after each ECAE pass are analyzed and the changes are discussed with respect to the initial texture.
