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 …

Indexable insert tools for machining operations are in service exposed to high temperatures
and cyclic mechanical loads. Secondary hardening steels such as hot-work steels are …

EUROFER97 is one of the candidate materials for structural components of fusion nuclear
reactors (ie ITER and DEMO). Due to the plasma instabilities and cyclic operating …

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 …

The low-cycle fatigue behavior of indigenously developed modified 9Cr–1Mo steel has been
evaluated using a constant strain rate (1× 10− 3 s− 1) at ambient temperature (25° C) and at …

Low alloy wear-resistant martensitic steels are increasingly prevalent in moderate-to-high
temperature applications in machinery. In this study, the reciprocating sliding wear behavior …

A multiscale characterization of the microstructural evolutions taking place in 9 to 12 pct Cr
martensitic steels subjected to fatigue and creep-fatigue (CF) loadings is presented …

Utilizing the hardness measurement, an attempt is made to study the tempering kinetics of
DM hot-work die steels, combined with scanning electron microscopy (SEM) and …

The work concerns research related to the assessment of the influence of the impact of the
steel grade used for forging punches in terms of the durability of tools used in the precision …

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 …
