Cyclic tests with or without tensile holding periods were conducted in air at 823K on a
modified 9Cr–1Mo martensitic steel. In addition to stress–relaxation fatigue (RF) tests with a …

In this paper, the analysis of the low cycle fatigue behavior of P91 steel is presented. First,
experimental tests are performed to recognize different aspects of material behavior. Then …

In order to identify the microstructural mechanisms leading to the softening effect usually
presented by martensitic steels under cyclic loadings (with or without hold times), a study of …

A series of uniaxial strain-controlled fatigue tests were performed at 650° C to explore the
high-temperature low cycle fatigue (LCF) behavior and corresponding microstructure …

This study examines the cyclic plastic deformation behavior and microstructural
development of a dual phase steel in both symmetric and asymmetric cycling in strain and …

The low cycle fatigue (LCF) behaviour of a dual phase (DP) steel with different martensite
volume fractions has been investigated, with particular focus on fatigue life, cyclic …

Detailed TEM and EBSD measurements were carried out to quantify the microstructural
evolutions and to identify the physical mechanisms taking place during fatigue and creep …

Atomic force microscopy and high resolution scanning electron microscopy were used to
find the true surface relief corresponding to persistent slip markings emerging from …

This study investigates the relationship between the microstructural evolution and low cycle
fatigue behavior of 316H austenitic steel to understand its performance at 550° C in …

The objective of the paper is to understand the mechanism of early stage crack formation in
the low cycle fatigue of a martensitic steel with a complex and hierarchic microstructure. As a …
