Inconel 718 specimens were additively manufactured via selective laser melting (SLM) and
subjected to different post-process heat treatments. Performance under monotonic and …

ABSTRACT The Inconel 718 (IN718) superalloy is commonly used as a component in
industrial gas turbines due to its excellent corrosion resistance and high-temperature …

Total strain-controlled low cycle fatigue (LCF) tests of a nickel based superalloy were
performed at 650° C. Various hold times were introduced at the peak tensile strain to …

For the fatigue reliability analysis of aeroengine blade-disc systems, the traditional direct
integral modelling methods or separate independent modelling methods will lead to low …

A dislocation density based crystal plasticity model is developed to account for the
precipitate induced cyclic softening in IN718. The new model treats the interaction between …

Low cycle fatigue (LCF) seriously affects the performance and reliability of turbomachinery
like aeroengine. Probabilistic LCF assessment can effectively quantify risk and improve …

This study investigates the relationships among the high-cycle fatigue life, surface
roughness, and additive manufacturing processing parameters in laser powder bed fusion …

Cyclic deformation of polycrystalline Ni-based superalloys leads to cyclic hardening
followed by softening, in terms of the mechanical response. A micromechanical constitutive …

Abstract Effects of strain amplitude ranging from 0.2% to 1.0% on the low-cycle fatigue
properties of Inconel 617 alloy at 700° C were studied. Much attention was paid to reveal the …

High-temperature low-cycle fatigue experiments were performed at different strain rates on
nickel-based superalloy MAR-M247. Furthermore, slow-fast, fast-slow and dwell-fatigue …
