Modelling of cavity nucleation under creep-fatigue interaction

Mechanics of Materials, 2021
Abstract A cavity nucleation model under creep-fatigue interaction, abbreviated as CH model, has been established. The key aspect of the CH model is accounting for the creep deformation through a self-consistent scheme. This allows the combined effect of grain boundary sliding (GBS) and crystal deformation on cavity nucleation to be assessed in Type ...

Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

Advanced Engineering Materials, EarlyView.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Creep-fatigue interaction in power plant steels [PDF]

Materials at High Temperatures, 2011
The consideration of a steel’s resistance to creep-fatigue crack initiation and development is an important part of the integrity assessment of high temperature power plant components. Defect-free or defect assessment procedures may be employed depending on the product form from which the component is manufactured, and the criteria adopted for design ...
