Scaling of damage mechanism for additively manufactured alloys at very high cycle fatigue [PDF]

Scientific Reports
A comparative analysis of fracture mechanisms in high- and very high- cycle fatigue (HCF, VHCF) regimes was carried out based on the results of multifractal analysis of the fracture surfaces of additively manufactured 316L stainless steel samples.

VHCF of the 3D-Printed Aluminum Alloy AlSi10Mg

Inventions, 2023
The paper is focused on the very high cycle fatigue (VHCF) properties of aluminum alloys proceeded in two different technological procedures. The hot-rolled D16T alloy is compared with the selected laser melting (SLM) AlSi10Mg alloy.

Very High Cycle Fatigue (VHCF) of notched specimens: a review

Fracture and Structural Integrity
A large number of mechanical components are subjected to fatigue loading beyond 106 cycles. The VHCF behaviour of smooth specimens has been extensively investigated in the recent years, even if more efforts are necessary to reveal the mecahnism ...

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).

Very High Cycle Fatigue of Welds: A Review

Metals, 2023
The design life of welded structures and components extends into the very high cycle fatigue (VHCF) regime across various applications. However, the availability of data on the fatigue behaviour of welded joints in the VHCF regime is limited ...

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.

Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]

MATEC Web of Conferences, 2018
Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Ultrasonic VHCF Tests on Very Large Specimens with Risk-Volume Up to 5000 mm³

Applied Sciences, 2020
The research on the size-effects in Very-High-Cycle Fatigue (VHCF) has recently drawn the attention of several scholars. The fatigue cracks in VHCF originate from the largest defect present within the loaded material volume (risk-volume) and the larger ...

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
