Abstract

In this study, recrystallization textures of monolithic pure Cu and alloyed Cu - C19210, with and without Nb reinforcement were investigated. Roll-bonded samples of different layered length scales were deformed to reductions of 70-90% and annealed at temperatures between 300°C and 800°C for 0.5 hours. We found that the Cube and {215}<211> orientations were the dominant components in the recrystallized texture of monolithic pure Cu and alloyed Cu respectively. However, rolling texture was retained for the sub-micron Cu layers of the composites. X-ray analysis and EBSD was used to study the recrystallization evolution of the Cu in the composites. We also propose a term - "confined recrystallization" to explain the effect of the length scale of the Cu layer thickness on the recrystallization texture and microstructural evolution especially in the sub-micron range.
