3

 

HQ shortened 42% at 800°C, 10-6/sec and 1200 MPa; regime 2 dislocation creep.

4

 

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

6

 

BHQ shortened 50% at 800°C, 10-6/sec and 1200 MPa ('wet'); regime 2 dislocation creep.

7

 

BHQ deformed by a combination of sinistral simple shear (g = 2.1) and shortening (~50%) at 800°C, 10-5/sec and 1200 MPa; regime 2 dislocation creep.
