Inconel 718 is a highly valued material in the aerospace and nuclear industries due to fact of its exceptional properties. However, processing this quite difficult, especially through machining processes. Machining results rapid tool wear, even when low removal rates are considered. In study, instrumented turning experiments were employed evaluate machinability alloy using PCBN tools while asse...

The characterization of Ni-based superalloy Inconel® 718 fabricated by powder-based laser fusion process was performed to study microstructural evolution and accompanying mechanical properties as-deposited post-heat-treated material. current effort employs a low volumetric energy density during the deposition. X-ray diffraction, optical, scanning electron microscopy were done for characterizati...

IN 718 is the most utilized nickel-based high-temperature alloy today. It widely adopted in important fields such as aerospace, energy and chemicals, one of few alloys for which parts can be fabricated using additive manufacturing. There a lack research on effect Si structure properties at microscopic scale. In this paper, doping γ-phase was investigated by first-principles calculations CASTEP ...

Electric Discharge Machining is a non-conventional machining process, used to machining difficult to machine materials. The major problem faced while doing EDM is high tool wear rate, end wear, corner wear , surface roughness and low material removal rate,. In this research work experimental investigations have been made to find the machining characteristics of high density ultra fine graphite ...

The widely adopted temperature for solid solution heat treatment (ST) the conventionally fabricated Inconel 718 is 1100 °C a hold time of 1 h or less. This ST scheme is, however, not enough to dissolve Laves and annihilate dislocations completely in samples with Laser metal powder bed fusion (L-PBF) additive manufacturing (AM)-Inconel 718. Despite this, highest hardness obtained after aging tem...
