Arkansas novaculite (original d = 5 µm) shortened 54% at 900°C, 10-6/sec and 1200 MPa ('wet'); transition between regime 2 - 3 dislocation creep.

Arkansas novaculite with an original grain size of 5 mm which has been shortened 54% at 900°C, 10-6/sec and 1200 MPa, with ~0.2 wt % water added. This sample had the same steady state flow stress as the quartzite in photo #10; in this case dynamic recrystallization has involved an increase in grain size to essentially the same size developed in the quartzite.
