A possible application of a metal powder composition made high-temperature nickel-based alloy with high heat strength (the material is analogous to Inconel 718) in selective laser melting (SLM, an additive manufacturing technology) was considered. Peculiarities formation the course have been researched, and mechanical properties were determined. The effect thermal treatment mode on characterist...

The residual stress and surface roughness enhancement of ground surfaces can decrease the lifetime workpiece by reducing its fatigue life. It is critical to accurately predict minimize toughness in order enhance efficiency part production using grinding operations. A virtual machining system developed research work integrity during operations Inconel 718. cutting temperature calculated alloy Jo...

Electrical Discharge Machine (EDM) parameters have a significant influence on machining characteristic like material removal rate (MMR) and tool wear rate (TWR). Inconel 718, which is widely used in the Medical, Marine, Architectural and food processing industries, is used as a work material. The tool electrode materials used are brass. Experiments are conducted using face centered central comp...

This work focused on the effects of laser energy density relative density, microstructure, and microhardness Inconel 718 alloy manufactured by selective melting (SLM). The microstructural architectures, element segregation behavior in interdendritic region evolution laves phases as-SLMed IN718 samples were analyzed optical metallography (OM), scanning electron microscopy (SEM), dispersive spect...

Inconel 718 is a typical hard-to-machine material that requires thermally enhanced machining technology such as laser-assisted milling. Based upon finite element analysis, this study simulates the forces in the laser-assisted milling process of Inconel 718 considering the effects of grain growth due to c0 and c00 phases. The c0 0 phase is unstable and becomes the d phase, which is likely to pre...

To cut the cost of laser powder bed fusion (LPBF) process, which is much higher than that traditional manufacturing an effective implementation optimization analysis needed. The study investigated LPBF Inconel 718 alloy with Taguchi method and principal component (PCA), covering four control factors at three levels in process. It focused on mechanical properties, namely tensile strength, elonga...
