Figure 4

Experimental creep data presented as strain vs. time (h) (ε(t) curves) in (a,c,e) and as logarithmic strain rate vs. strain (\(\mathrm{log}\,\dot{\varepsilon }(\varepsilon )\) curves) in (b,d,f). (a) and (b): 1400 °C, (c) and (d): 1500 °C, (e) and (f): 1600 °C. The numbers next to the curves indicate tensile stresses in MPa. Only one experimental condition was applied two times (170 MPa at 1500 °C). The curves are shown in (c,d). One experiment (137 MPa, 1500 °C, ε = 2.9%) was interrupted in the very early stages of creep (end of curve marked with an open square) and subsequently investigated with SEM. The end of an experiment which proceeded through rupture under the same creep conditions (137 MPa, 1500 °C, εR = 72%) is marked with a filled square. This specimen was also investigated with SEM.
