Recommendation for creep and creep-fatigue assessment for P91 components

Rami Pohja, Stefan Holmström, Hyeong-Yeon Lee

Research output: Book/ReportReport

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.
