Effect of Rolling Friction on the Development of {111} Texture in A1050 Aluminium Sheets

Article Preview

Commercially pure aluminum (A1050) sheets have been cold- rolled in vacuum, to obtain high friction between rolls and sheet. This cold-rolling in vacuum successfully introduced large shear deformation near the sheet surface. The shear strain is the highest at the sheet surface, and rapidly decreased to zero at the quarter thickness. These high shear strains are sufficient enough to produce {111} and {001} cold- rolling, or shear texture. Conventional cold-rolling texture such as (001) [100], is naturally observed at the mid-thickness. It is confirmed that a high shear strain and probably steep strain gradient through thickness have a sufficient effect on the increase in {111} cold-rolling texture near the sheet surface. {111} cold-rolling texture is proved to be effective in the evolution of {111} recrystallization texture. This development will be discussed based on the cold-rolling texture change.
