摘要：

The present work deals with the creep behaviour of 9 - 12% Cr steels in the steady state ( secondary) creep regime in order to enable a more detailed and exact description of the creep rupture strength on the basis of the Monkman Grant relationship. Special attention is paid to the microstructural aspects. The steady state creep behaviour has been investigated by evaluating the creep rate and the change of stress exponent of already established grades of high temperature creep resistant steels.
