Effect of sulfur on the solidification and segregation in Inconel 718 alloy
Materials Letters, 1997The effect of sulfur on the solidification and segregation in Inconel 718 alloy was studied. Sulfur is extremely depleted in the matrix, slightly dissolved in the Laves phase and NbC, and seriously segregated as sulfides. Except for the needle-like Y-phase ((Nb, Ti)(2)SC), a globular sulfide was newly found to form following the precipitation of the ...

Ni3Nb alloy species in oxide surfaces of INCONEL 718
Metallurgical Transactions A, 1986INCONEL 718 has been studied by Auger and X-ray photoelectron spectroscopy to determine the effect on the surface stoichiometry caused by heat treating in argon to 1000 C. Two surface regions are produced, the one closest to the argon-metal oxide interface being rich in O, Ti, Al, and Cr, and the one closest to the alloy being rich in O, Al, and Nb ...

Effect of microstructure on electrical conductivity of Inconel 718 alloys
Materials Science and Technology, 2015The microstructural evolution of Inconel 718 during aging processes has been studied through a combination of eddy current testing, X-ray diffraction analysis, and metallography and hardness measurements. Measurements were carried out in samples subjected to eight different heat treatment cycles, between 620 and 1035°C for 1–18 h. Different amounts of

FEM-Based Hot Machining of Inconel 718 Alloy
2020Finite element simulation of metal cutting process has acquired much attention by many researchers in the recent past since it is a robust tool to estimate the machining process variables, which are hard to get experimentally. It is well known that machining of hard to cut materials causes large cutting forces, which is responsible for excessive tool ...

The evolution of delta-phase in a superplastic Inconel 718 alloy
Journal of Materials Science, 2007An Inconel 718 sheet alloy was tested in tension at a temperature of 965°C and an initial strain rate of 10−4 s−1 corresponding to the conditions for optimum superplastic deformation. Detailed observations and quantitative measurements record the evolution of the δ-phase during tensile deformation.

Simulation of creep cavity growth in Inconel 718 alloy
Materials Science and Engineering: A, 2011Nickel base superalloys provide significant improvements relative to the limitations in the areas of creep resistance, oxidation, low cycle and high cycle fatigue resistance. Since these materials are being pushed to limits of their capability in gas turbine applications, accurate mathematical models are needed to predict the service lives of the high ...

The erosion behaviour of Inconel 718 in molten A380 alloy
Scripta Materialia, 1999The erosion of materials in molten metals and alloys is of considerable importance in engineering applications such as liquid metal handling and containment in the metallurgical industry. So far, available results on the interaction of nickel and aluminum, including solid nickel/solid aluminum and solid nickel/liquid aluminum systems, are all from the ...
