Abstract
:1. Introduction
2. Experimental Section
3. Results and Discussion
3.1. Microstructure and Texture of Rolled Copper Sheets
3.2. Microstructure and Texture of Annealed Copper Sheets
4. Conclusions
- The deformation textures of S, Copper and Brass were progressively enhanced with the increase in cold-rolling reduction. When the rolling reduction exceeded 60%, the orientations along the α-oriented fiber converged towards Brass, and the orientation density of the β fiber obviously increased.
- The recrystallization texture was significantly influenced by the cold-rolling reduction. After a 60% cold-rolling reduction, Copper and S texture components gradually decreased, while the {011}<511> recrystallization texture component formed with an increase in annealing temperature. Following an 87% cold-rolling reduction, a strong Cube texture formed, and other textures were suppressed as annealing temperature increased. The strong Brass and S deformation texture favored the formation of a strong Cube annealing texture.
- The annealing twin density decreased with the increase in annealing temperature, and more annealing twin boundaries formed in oxygen-free copper sheets with the increase in cold-rolling reduction.
