HQ shortened 64% at 800°C, 10-6/sec and 1200 MPa; regime 2 dislocation creep.

HQ shortened 64% at 800°C, 10-6/sec and 1200 MPa (regime 2 dislocation creep). This higher strain sample also shows moderately homogeneous flattening of original grains. There is a greater volume % of recrystallized grains, again mostly located on original grain boundaries. The 'puckered' appearance within many original grains is due to subgrains. (W370)
