Abstract

The short-term creep behaviour of AISI 316H stainless steel was investigated in the temperature range 800 degrees - 1300 degrees C. The tests show that the secondary creep rate element of s follows the Norton power law, but for the tertiary creep rate element of t, an empirical expression was obtained. The acceleration of tertiary creep is postulated to be caused by the joint action of a stress dependent process and a time-dependent process which correspond to intragranular deformation and intergranular damage respectively.
