In this study, the failure analysis and design improvements of a steel piston for a marine
engine were performed. In order to assess the high-cycle fatigue performance of the steel …

In the present study, fatigue damage evolution of Inconel 617 at 600° C and 700° C was
investigated by using an in situ scanning electron microscope (SEM) fatigue test. The fatigue …

Combined tensile and bending fatigue (CTBF) behavior and failure mechanism of a blade-
like specimen, made of a Ni-based alloy DZ125, are experimentally investigated. In order to …

The study presents an insight into the deformation mechanisms under high cycle fatigue-
creep interaction (HCF-creep interaction) in a Ni-based superalloy (Alloy 617 M), using …

In this study, we propose a new two‐scale fatigue model based on continuum damage
mechanics. A representative volume element (RVE) consisting of microinclusions and a …

The cyclical behavior of Alloy 617 was examined at 25° C and high temperatures of 800,
850, 900, and 950° C in air to obtain its fatigue life curves. The specimens tested at 25, 800 …

The present work is aimed at a re-evaluation of the Haigh diagram incorporating the effect of
creep on HCF. HCF testing was carried out at 973 K with varying mean stress (σ m) and …

Nickel-based alloy 617 with controlled composition (designated as alloy 617M) and
ferritic/martensitic 10% Cr steel are candidate materials for the steam rotor forgings in the …

The present study aims at understanding the mechanisms of fatigue endurance through high-
cycle fatigue (HCF) behavior of Alloy 617M at varying temperatures, ranging from 300 to …

Interaction of fatigue and creep behavior is the dominant failure mode for high cycle or very
high cycle fatigue under high mean stress at high temperature. As for large rotating …
