BHQ shortened 50% at 800°C, 10-6/sec and 1200 MPa, with ~0.2 wt % water added. (The added water has the same effect as increasing the deformation temperature by ~100°C). Deformation occurred by regime 2 dislocation creep; note the homogeneously flattened original grains. The recrystallized grains are larger than those in slide #4 because of the added water. BA20 x 10.
