...Nils Potthoff; Jan Liß; Petra Wiederkehr High-strength and corrosion-resistant materials, such as the nickel-based superalloy Inconel 718, are widely used in the energy and aerospace industries. However, machining these materials results in high process forces and significant tool wear. This tool...

...Nils Potthoff; Ankit Agarwal; Florian Wöste; Petra Wiederkehr; Laine Mears Tool wear plays a decisive role in achieving the required surface quality and dimensional accuracy during the machining of Inconel 718-based products. The highly stochastic phenomenon of tool wear, particularly in later...

... cooling rate was assumed when constructing the CCT diagram. Inconel 718 parts fabricated by selective laser melting were analyzed. The accumulated duration required for γ′/γ″ precipitate formation was found to shift from at least 432 s to about 83.38 s. The large difference in the duration (around 518...

... strain extrusion machining. The modified Zerilli–Armstrong constitutive relation is implemented in a finite element model of large strain extrusion machining of Inconel 718 to analyze the influence of process parameters, i.e., the chip compression ratio and tool–chip friction, on deformation, effective...

...Andrea De Bartolomeis; Stephen T. Newman; Dirk Biermann; Alborz Shokrani Inconel 718 is the most used nickel superalloys with applications in aerospace, oil and gas, nuclear, and chemical industries. It is mostly used for safety-critical components where the condition of the surface...

... Inconel 718 by AFM, aiming to verify the feasibility of AFM on internal surface quality improvement. The surface evolution process was modeled, and the effects of process parameters on surface and subsurface quality were evaluated. The results show that good surface roughness was obtained at the medium...

...M. Barletta; D. Ceccarelli; S. Guarino; V. Tagliaferri The relatively new technique of fluidized bed assisted abrasive jet machining (FB-AJM) is applied to finishing the inner surfaces of tubular Inconel 718 components. The effects of abrasive size, jet pressure, and machining cycle were evaluated...
