Abstract Alloy 718 is a Ni-Fe-based superalloy, which has been successfully adapted to
powder bed fusion (PBF) additive manufacturing because of the alloy's adaptability with …

Inclusions in wrought superalloys significantly affect the stability of the alloy properties and
limit their use and development in aeroengines and other applications. The types and …

Fatigue crack nucleation in a powder metallurgy produced nickel alloy containing a non-
metallic inclusion has been investigated through integrated small-scale bend testing …

Ultrasonic fatigue tests were performed to investigate high and very high cycle fatigue
behaviors of a laser additively manufactured Inconel 718 (IN718) alloy in the as-deposited …

The microstructural sensitivity of fatigue short crack path and its propagation rate in a Ni-
based superalloy GH4169 manufactured by laser powder bed fusion (LPBF) was …

In this study, the high cycle and very high cycle fatigue behavior of the GH4169 superalloy
was investigated. The results of the fatigue tests demonstrated that failures in the high cycle …

This study investigates the effects of two different shot peening techniques, conventional
shot peening (CSP) and ultrasonic shot peening (USP), on the very high cycle fatigue …

Additive Manufacturing (AM) has increasingly been used to fabricate parts in aerospace
applications, which may require service lives beyond ten-million cycles due to the imposed …

A single crystalline (SX) nickel-based superalloy additively manufactured (AM) by electron
beam-based powder bed fusion (PBF-E) was investigated under very high cycle fatigue …

The fatigue crack initiation at twin boundary (TB) and the life prediction of IN718 alloys in the
high cycle fatigue (HCF) regime and very high cycle fatigue (VHCF) regime were …
