Title

Research Paper / Trasformations : Effect of Annealing Temperature on the Evolution of Annealing Texture in Aluminium Foils

허무영Moo Young Huh, 이수태Soo Tae Lee, 이현규Hyun Kyu Lee

Abstract

The effect of annealing temperature on the evolution of the annealing texture in high purity aluminium foils was studied by X-ray texture measurements and microstructure observations. Upon annealing at a lower temperature, the preferred orientations in the annealing texture were quite similar to those found in the cold rolling texture, although the foils were completely recrystallized in the microstructure. Annealing at a higher temperature led to the formation of the strong cube texture. The lowest annealing temperature at which the cube texture begins to develop was dependent on the purity of aluminium foils. The orientation density of the cube orientation increased with the purity of the fails: Since the development of the cube orientation seemed to be related with the size of annealed gains, it was concluded that the grain growth played an important role in the evolution of the cube texture.
