    Abstract

    This report describes the experimental work carried out by the various partners within the MATTER Task 7.1 in support to the improvement of the design rules, especially for 9%Cr ferritic-martensitic steel (P91). The tests performed are aimed at evaluating the extent to which component design rules written for materials with a greater ductility and which have a hardening behaviour under cyclic loading (for example austenitic stainless steels), are applicable to P91 material which instead is typically characterized by cyclic softening. According to the MATTER DoW (Description of Work) document, these tests include ratcheting validation tests, low cycle fatigue (LCF) tests, creep-fatigue and relaxation-fatigue tests, creep-crack growth (CCG) and fatigue-crack growth (FCG) tests, tensile tests on aged P91 as well as pure creep tests including also tests in support to the definition of the negligible creep domain. Specific objective of the work is the creation of an experimental dataset that will be used in other MATTER Tasks (T4.2 and T4.3) as the basis to improve ratcheting and creep-fatigue rules in European Codes, in particular with a focus on the efficiency diagram method and the creep-fatigue interaction diagram in RCC-MRx.
