Notes:
In the present work, a thorough investigation of evolution of microstructure and texturehas been carried out to elucidate the evolution of texture and grain boundary character distribution(GBCD) during Equal Channel Angular Extrusion (ECAE) of some model two-phase materials,namely Cu-0.3Cr and Cu-40Zn. Texture of Cu-0.3Cr alloy is similar to that reported for purecopper. On the other hand, in Cu-40Zn alloy, texture evolution in α and β (B2) phases areinterdependent. In Cu-0.3Cr alloy, there is a considerable decreases in volume fraction of low angleboundaries (LAGBs), only a slight increase in CSL boundaries, but increase in high angle grainboundaries (HAGBs) from 1 pass to 4 passes for both the routes. In the case of Cu-40Zn alloy, thereis an appreciable increase in CSL volume fraction
