VHCF Response of Two AISI H13 Steels: Effect of Manufacturing Process and Size-Effect [PDF]

Metals, 2019
In the last decades, the fatigue lifetime of structural components has increased significantly and in many industrial applications (aerospace, automotive, and energy production industry) is even larger than 1010 cycles.

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.

Variations of VHCF Characteristics by Microstructure of a Spring Steel to UNSM Treatment [PDF]

한국해양공학회지
The bainitic structure resulting from the austempering of spring steel exhibits high strength and ductility. On the other hand, there appears to be no study on the effects of very high cycle fatigue (VHCF) and ultrasonic nanocrystal surface modification (

Influence of the annealing and defects on the VHCF behavior of an SLM AlSi10Mg alloy [PDF]

Fatigue and Fracture of Engineering Materials and Structures, 2019
AbstractIn the paper, the influence of the annealing temperature on the Very High Cycle Fatigue (VHCF) of AlSi10Mg specimens produced through selective laser melting (SLM) is experimentally assessed. VHCF tests at 20 kHz are carried out on Gaussian specimens subjected to a heat treatment suggested by the system supplier (heating for 2 hours to 320°C ...

Fatigue Behavior of Metastable Austenitic Stainless Steels in LCF, HCF and VHCF Regimes at Ambient and Elevated Temperatures

Metals, 2019
Corrosion resistance has been the main scope of the development in high-alloyed low carbon austenitic stainless steels. However, the chemical composition influences not only the passivity but also significantly affects their metastability and ...

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.

Thickness debit effect of Ni-based single crystal superalloy thin-walled specimens in the VHCF regime based on a vibration fatigue test

Journal of Materials Research and Technology
This paper proposes a novel vibration fatigue testing methodology of thin-walled specimens in the very high cycle fatigue (VHCF) regime, with the lifetime up to 109 cycles. A series of novel thin-walled specimens for the single crystal superalloy DD6 are

Environment-dependent very high cycle fatigue (VHCF) in metal additive manufacturing (AM): A critical and emerging paradigm

Review of Materials Research
This overview critically instructs the emerging, but less explored, field of environment-dependent very high cycle fatigue (VHCF) in metal additive manufacturing (AM). As AM technologies are increasingly adopted for structural applications, understanding

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).
