Recrystallization texture of aluminum bicrystals with S orientations deformed by channel die compression

The texture changes during recrystallization in high-purity aluminum bicrystals with S orientations, e.g. (123)[412̄]/(123)[4̄1̄2] and (123)[412̄]/(1̄2̄3̄)[412̄], deformed by channel die compression were investigated by Blicharski et al. There was no 〈111〉 rotational relationship between the recrystallized and the deformed matrix phases. This result could be explained by the strain energy release maximization model, in which the direction of absolute maximum internal stress due to dislocations in the deformed matrix becomes parallel to the minimum Young’s modulus direction in recrystallized grains, whereby the energy release during recrystallization can be maximized.
