BHQ shortened 60% at 800°C, 10-6/sec and 1200 MPa (regime 2) and then statically annealed at 900°C for
120 hours. The deformation microstructure has been completely replaced by strain-free polygonal recrystallized
grains, but the pattern and the strength of the c-axis crystallographic preferred orientation has not changed.
Compare this slide with #12, which shows a sample dynamically recrystallized at high temperature; in the
annealed sample the grain boundaries are straighter, but both samples were quenched. Would differences be
preserved and noticeable in naturally deformed (and possibly annealed) samples? AN9 x10.
