Very HIgh Cycle Fatigue (VHCF) behavior of high strength alloys : A literature review

, 2023
Very High Cycle Fatigue (VHCF) response of metallic materials is considered of significance importance, particularly for high- demanding applications. Since it is proved that most of the engineering materials do not exhibit a conventional fatigue limit ...

Investigation of the mechanical work during ultrasonic fatigue loading using pulsed time-resolved X-ray diffraction [PDF]

Journal of Synchrotron Radiation
In the energy production and transportation industries, numerous metallic structures may be subjected to at least several billions of cycles, i.e. loaded in the very high cycle fatigue domain (VHCF).

A review of the research on the VHCF test technology for aero-engine typical materials

Hangkong gongcheng jinzhan, 2023
As the most critical and core part of the aircraft, the aero-engine has been serving in extreme environ-ment such as high temperature and high load for a long time. Fatigue failure is one of the main causes of engine structure failure.

Ultra-high frequency vibration fatigue of DD6 single crystal superalloy simulating thin-walled specimens

Journal of Aeronautical Materials, 2023
The effect of specimen thickness on the very high cycle fatigue （VHCF） properties of DD6 nickel-based single crystal superalloys for turbine blades with hollow air-cooled structure was investigated. Based on the finite element method （FEM）, a thin-walled
