Turbine bladed disks normally operate under complex loadings coupling with uncertainties
originate from multiple sources, including material variability, load variation and geometrical …

In the present study, a computational-experimental framework is developed for fatigue
reliability assessment of turbine bladed disks. Within the framework, the overspeed testing is …

Impellers and blades are the key components of turbomachines, and fatigue is the main
failure mode of impellers and blades. The status and progress of fatigue research on …

Fatigue failure can be considered as the main failure mode of impellers in various kinds of
turbomachinery, especially centrifugal compressors. Studying and understanding the fatigue …

Taking a compressor impeller with a pressure ratio less than 3 as the research object, the
influence of 3D printing on the fatigue crack propagation life of the compressor impeller is …

Fatigue life assessment of centrifugal compressor impellers has been a critical issue in
industrial practice and application. In this paper, both centrifugal load and aerodynamic load …

Traditional polishing on an integral impeller is labour intensive owing to its complicated
curved surfaces. In this study, a novel rotary chemical mechanical polishing (R-CMP) for an …

In this study, a novel process of chemical mechanical polishing (CMP) is proposed for
FV520B steel. A novel environmentally friendly CMP slurry without any strong acids, alkalis …

The corrosion fatigue behavior of FV520B steel in water and salt-spray environments at
different temperatures is the focus of this study. Temperature has a significant effect on the …

Due to the rapid heating-cooling process and unstable keyhole, pore defects are easily
formed during the high energy beam-powder additive manufacturing (AM) process, posing …
