Abstract
This report is based on the results and experience gained
in assessing both public domain and MATTER data, some
previously reported in the MATTER deliverable D4.5:
"Creep-fatigue interaction rules for P91" and some
assessed here. A number of methods, including interaction
diagram based methods and simplified methods, have been
compared for predicting the creep-fatigue life of P91
steel. The effect of cyclic softening on creep properties
have been considered in the evaluations presented in this
report. The purpose of this report is to give
recommendations for creep and creep-fatigue assessment
for components made of X10CrMoVNb9-1 (P91) steel.
