Failure diagnosis invariably involves consideration of both associated material condition
and the results of a mechanical analysis of prior operating history. This Review focuses on …

Strain controlled fatigue of P92 steel with various strain hold dwells introduced at the peak
loading point were conducted at 625° C. Two features which depend on the cycle and strain …

The goals of this paper are:(i) to review the mechanisms of cyclic deformation, damage
accumulation and crack propagation in three types of materials widely used in power …

The present article compares the cyclic behaviour of various 9–12% Cr steels, both
commercial grades and optimized materials (in terms of creep strength). These materials …

In the framework of the development of generation IV nuclear reactors and fusion nuclear
reactors, materials with an improved high temperature (≅ 650° C) mechanical strength are …

Symmetrical and asymmetrical strain cycling tests of X12CrMoWVNbN10-1-1 steel were
conducted at 873 K. Significant rate dependence, mean stress relaxation and continuously …

The degradation of tensile and creep properties is inevitable during high temperature
service operation. Hence this work aims to evaluate the effect of prior creep-fatigue …

Abstract Axial–torsional Low-Cycle Fatigue tests (LCF) and Thermo-Mechanical Fatigue
tests (TMF) were performed on a low-alloy martensitic steel for temperatures between 300° …

An improved unified cyclic viscoplastic material model for high temperature fatigue of P91
steel is presented. The primary enhancement over existing models is in relation to strain-rate …

In this article, strain-controlled Low-Cycle Fatigue (LCF) and fatigue–creep tests were
performed on Inconel 718 nickel-based superalloy at temperatures of 650° C and 730° C …
