Evaluation of Inconel 718 Creep Behavior
Defect and Diffusion Forum, 2012Superalloys are used primarily in aerospace applications. These applications require a material with high mechanical strength, good resistance to fatigue and creep, good corrosion resistance and ability to operate continuously at elevated temperatures.

High temperature deformation of Inconel 718
Journal of Materials Processing Technology, 2006Abstract Several technological applications demand materials able to have good mechanical performance at relatively high temperatures (as high as 650 °C). This performance must be kept constant during long periods at these high temperatures. Superalloys, and particularly Ni–Cr–Fe alloys (Inconel series) appear to be candidates to accomplish such ...

Superplastic behaviour of Inconel 718 sheet
Materials Science and Technology, 2000Inconel 718 is a nickel based alloy used extensively in the aerospace industry, having good service capabilities, in terms of strength and fatigue resistance, at high temperatures. Inconel 718, in the form of sheet, has the capability of being shaped using gas pressure forming techniques similar to those used for a number of aluminium and titanium ...

Strain hardening in underaged INCONEL 718
Metallurgical and Materials Transactions A, 1994INCONEL 718 is a commercial, precipitation-hardenable nickel iron-base superalloy, strengthened primarily by precipitates of the metastable [gamma][double prime] phase which is based on the composition Ni[sub 3]Nb and has an ordered body-centered tetragonal (DO[sub 22]) structure. An earlier investigation on the deformation mechanisms in this alloy has

Machining nickel base superalloys: Inconel 718
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 1998A series of machining experiments of Inconel 718 has been carried out using coated and uncoated carbides. The paper describes the effects of cutting variables (speed, feed and depth of cut) on cutting forces and tool life. Carbide tools in the form of 80° rhomboid shaped inserts without any chip breaker have been used at different cutting conditions ...

Time Dependent Response of Inconel 718
The time dependent response of precipitated hardened Inconel 718 is investigated experimentally. The experimental program is designed to determine the mechanical behavior of Inconel 718, which is extensively used in aerospace applications, at various temperatures, strain rates, and states of stress. Compression and tension tests are conducted at strainAaron Ressa +3 more
