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 …

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 …

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 …

Electron beam melting (EBM) and Selective Laser Melting (SLM) are powder bed based
additive manufacturing (AM) processes. These, relatively new, processes offer advantages …

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

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 …

This work provides a comprehensive characterization and analysis of deformation and
fatigue damage mechanisms in a nickel-based superalloy during ambient temperature …

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 …

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 …
