BHQ shortened 50% at 1200°C, 10-6/sec and 1200 MPa; regime 3 dislocation creep.

BHQ shortened 50% at 1200°C, 10-6/sec and 1200 MPa, in regime 3 dislocation creep. This sample has been completely dynamically recrystallized, to form relatively large polygonal grains which might at first appear 'annealed' (compare with photo #14). The higher the temperature of deformation, the more closely the rate of recovery can match the rate of deformation. (W857)
