Abstract
In this study the high temperatures were up to 2160 °C and the tensile stresses ranged from 133.83 to 213.46 MPa. Based on the creep experiment of single specimen method, the apparent activation energy and the stress exponent for steady-state creep were determined by the use of a self-made apparatus and an auto-testing system. Values of the apparent activation volume were provided and the creep mechanism has also been discussed.
