Electrochemical Broaching of Inconel 718 Turbine Mortises. [PDF]
Materials (Basel)The turbine mortise is a critical structural feature of turbine disks, and its manufacturing quality directly determines the performance and service life of aircraft engines. With the increasing application of advanced nickel-based superalloys, severe tool wear in conventional mechanical broaching of turbine mortises has emerged as a key limitation ...

DISCONTINUOUS DRILLING OF INCONEL 718
MM Science Journal, 2021 Inconel 718 as one of the most common nickel-base alloys is mainly characterized by its high-temperature strength. Thus, in particular drilling is subject to high tool wear due to high thermomechanical loads on the cutting edges. To reduce those effects an alternative process design of discontinuous drilling was developed which contains a periodical ...

Cold Rotary Forging of Inconel 718 [PDF]
Journal of Manufacturing Processes, 2019 The present work includes an in-depth study of microstructure and mechanical property development in a cold rotary forged component manufactured from Inconel 718 alloy. This work is pioneering in that there is no detailed study available in the literature focussing on cold rotary forging of Inconel 718. A tubular preform of 6 mm wall thickness was cold

Inconel 713C Coating by Cold Spray for Surface Enhancement of Inconel 718 [PDF]
Metals, 2021 Inconel 713C is a nickel-based superalloy usually considered as a material of poor weldability due to its susceptibility to hot cracking in the heat-affected zones. Cold spray, a solid-state deposition technology that does not involve melting, can be proposed as a methodology to deposit Inconel 713C for surface enhancement of other target components ...

Representing the superplasticity of Inconel 718
Journal of Materials Processing Technology, 2004 Abstract Modelling the superplastic process using finite element analysis can enable optimum process parameters to be determined and lead to a better understanding of the process. Constitutive equations, which accurately represent a material’s behaviour, are very important in the development of representative process models.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...
