Deformation and recrystallization in cross-rolled Al-Cu precipitation alloys

The deformation and recrystallization behaviour of single-phase f.c.c. metals have been studied mostly after conventional, uniaxial rolling. In this paper, the effect of both the presence of a second phase and the deformation path (i.e. straight rolling versus cross-rolling) on the evolution of microstructures and textures of an Al-3% Cu alloy are presented. The changes in the deformation and recrystallization texture are found to be complex, and it is not the deformation path nor solely the type of precipitate alone which produces the changes.
