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

Fatigue life prediction based on a deep learning method for Ti-6Al-4V fabricated by laser powder bed fusion up to very-high-cycle fatigue regime

, 2023
Microstructural defects and inhomogeneity of titanium alloys fabricated by laser powder bed fusion (LPBF) make their fatigue behaviors much more complicated than the conventionally made ones, especially in very-high-cycle fatigue (VHCF) regime.
