  The recrystallized grain size and texture in alloys can be controlled via the
microchemistry state during thermomechanical processing. The influence of
concurrent precipitation on recovery and recrystallization is here analyzed by
directly correlating (sub)grains of P, CubeND or Cube orientation with
second-phase particles in a cold-rolled and non-isothermally annealed Al-Mn
alloy. The recrystallized state is dominated by coarse elongated grains with a
strong P, weaker CubeND and even weaker Cube texture. The correlated data
enables orientation dependent quantification of the density and size of
dispersoids on sub-boundaries and subgrains in the deformation zones around
large constituent particles. A new modified expression for the Smith-Zener drag
from dispersoids on sub-boundaries is derived and used. The results show that
the drag on (sub)grain boundaries from dispersoids is orientation dependent,
with Cube subgrains experiencing the highest drag after recovery and partial
recrystallization. The often observed size advantage of Cube subgrains in Al
alloys is not realized due to the increased drag, thereby promoting
particle-stimulated nucleation (PSN). Relatively fewer and larger dispersoids
in deformation zones around large particles give a reduced Smith-Zener drag on
PSN nuclei, thus further strengthening the effect of PSN. Observations
substantiating the stronger P texture compared to the CubeND texture are a
higher frequency of P subgrains and a faster growth of these subgrains. The
applied methodology enables a better understanding of the mechanisms behind the
orientation dependent nucleation and growth behavior during recovery and
recrystallization with strong concurrent precipitation in Al-Mn alloys. In
particular, the methodology gives new insights into the strong P and CubeND
textures compared to the Cube texture.
