Fusion-based additive manufacturing (AM) has significantly grown to fabricate Nickel-based
superalloys with design freedom across multiple length scales. Several phenomena such as …

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 …

The use of aluminum (Al) alloys for additive manufacturing (AM) has recently gained
significant attention, specifically in the aerospace industry. This has been resulting in …

Due to exceptional strength/stiffness to weight ratio, aluminum (Al) alloys are being
extensively used in many exclusive applications. The microstructure, and consequently, the …

In this study, the effect of various surface treatments, including sand-blasting, drag-finishing,
turning, grinding, and grinding+ drag-finishing, on surface roughness and fatigue properties …

Ultrasonic fatigue testing is a resourceful (time-and cost-saving) approach to assess the
dynamic failure of materials in the gigacycle range (ie, when the number of cycles to failure …

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 …

Fatigue cracks in additively manufactured (AMed) Inconel 718 (IN-718) in machined surface
condition often initiate from persistent slip bands (PSBs) unlike other popular AM alloys such …

GH4169 joints manufactured by Linear Friction Welding (LFW) are subjected to tensile test
and stair-case method to evaluate the High Cycle Fatigue (HCF) performance at 650℃. The …

Ultrasonic high-frequency fatigue testing differs from conventional low-frequency fatigue
testing in strain rate and cyclic loading. Ultrasonic fatigue has a resonance frequency of …
