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 ...

Defects in Nickel-Base Superalloys
JOM, 1987In the sixty years since age-hard-enable, nickel-base superalloys were first identified, the compositional and microstructural features of these high-performance metals have changed markedly—from the early Nimonic (INCO trade name) 80A (a wrought alloy of essentially four elements) to today’s family of wrought from ingot, powder metal, cast and ...

Aluminide Coatings for Nickel Based Superalloys
Surface Engineering, 2004A number of aluminide coatings have been developed which are modified by additional elements (noble metals, Cr and reactive elements such as Y and Hf). This results in a marked improvement in their corrosion resistance. In the present paper, aluminide coatings are reviewed. The hot corrosion and oxidation resistance of these coatings in laboratory and

Additive Manufacturing of Nickel-Based Superalloys
Volume 1: Additive Manufacturing; Bio and Sustainable Manufacturing, 2018Additive manufacturing enables the design of components with intricate geometries that can be manufactured with lead times much shorter when compared with conventional manufacturing. The ability to manufacture components out of high-performance metals through additive manufacturing technologies attracts industries that wish to develop more complex ...

The so-called nickel-base superalloys or high-strength high-temperature alloys are, in general, modifications of the corrosion- and heat-resisting alloys of the types discussed in Chapters 3 and 4. Their improved strength and creep resistance at elevated temperatures have been developed by including elements which will produce a stable hard phase or ...

NICKEL-BASE SUPERALLOY OXIDATION
1967Abstract : A program to determine the phenomenological oxidation behavior of five commercial nickel-base alloys (IN-100, SM-200, Inco 713C, Rene 41, and U- 700) and one experimental alloy (Rene Y) is described to assure the intelligent application of these alloys and aid in the development of alloys with improved surface stability.

The recrystallization of nickel-base superalloys
Journal of Materials Science, 1981The effects of recrystallization on the γ′ distribution in four nickel-base superalloys of varying γ′ volume fraction (Nimonics PE16, 80A and 115, and Udimet 720) have been studied by transmission electron microscopy. These effects are explained in terms of high solubility and diffusivity in the recrystallization interface, and it is suggested that ...

Automated modeling of nickel‐based superalloys
PAMM, 2017AbstractThroughout the last 60 years, nickel (Ni) based superalloys have been the standard high‐temperature material used in mobile and stationary gas turbines. The ever increasing temperatures necessitate further improvements of those alloys, foremost, enhancing their creep‐resistance.

Reverting foundry nickel-base superalloys
1986This work was part of a COST 50 project aimed at ways to make revert IN 100 less prone to soundness defects and associated property degradations. It was based on carrots cast from 5 master distinct master melts, which were evaluated through metallography and Differential Thermal Analysis. Recycling was shown to affect grain size and morphology, carbide
