This study presents a thorough literature review on the powder-bed laser additive
manufacturing processes such as selective laser melting of Inconel 718 parts. This article …

Powder metallurgy (PM) Ni-based superalloys are widely used for aeroengine turbine disc
applications due to their excellent mechanical properties and good corrosion resistance at …

In this paper, a comparative study of high-cycle fatigue tests (T= 650° C, f= 110 Hz, R= 0.1, K
t= 1) were carried out with wrought Inconel 718 and LAMed Inconel 718. The results show …

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 …

This study indicates that the kinetic rate constants of oxidation weight gain and thickening
both increase with the increasing content of O, N and S impurities. The oxide layer of the low …

The nonuniform microstructure of the as-built Inconel 718 superalloy fabricated by high-
deposition-rate laser directed energy deposition (HDR-LDED) brings about heterogeneous …

Oxide intrusions which formed ahead of the crack tip in an advanced nickel-based
superalloy after exposure to air at 650° C have been investigated by (scanning) …

The fatigue of TC17 titanium alloy at high temperature could present fatigue failure mode or
mixed failure mode with ductile cracks and local regions of fatigue cracks. For the former, the …

Low-temperature and short-time solution and aging heat treatment (1050℃, 15 min/WC+
720℃, 8 h/FC to 620℃, 8 h/AC) was proposed for laser repaired Inconel 718 components in …

The low cycle fatigue (LCF) and creep-fatigue behaviors of Ni-based GH4169 superalloy are
investigated by uniaxial strain-controlled fully-reversed testing at 650° C. Compared with …
