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...

Epidemiological studies have demonstrated higher frequencies of the O blood group and the nonsecretor phenotype of ABH antigens among patients suffering from peptic ulcers. Since Helicobacter pylori has been established as the main etiological factor in this disease, controversies about the associations of the ABO and Lewis blood group phenotypes and secretor and nonsecretor phenotypes in relat...

Tungsten inert gas (TIG) is currently one of the most widely applied welding technologies. However, arc energy divergence and high heat input conventional TIG can lead to defects in heat-input-sensitive alloys (such as Inconel 718). Introducing a fast-frequency pulsed current (≥20 kHz) creates process named tungsten (FFP-TIG). The behavior FFP-TIG has advantages over terms contraction, pressure...

A comparative study on the mechanical properties, scratch resistance, and localized corrosion (pitting crevice) of plasma-nitrided Inconel alloy 718 (UNS NO7718: IN 718) was carried out. Thermochemical treatment performed at low temperatures (400 450 °C) for 4 h. The formed layers with thicknesses 7.17 ± 0.89 µm 7.96 0.48 (450 °C). XRD nanohardness analyses indicated formation a hard layer comp...

Nickel superalloys occupy a reasonably broad niche in the industry. One of this group’s most common and well-known alloys is Inconel 718. Parts from 718 are used aerospace, energy, automotive, some other vital industries, which creates demand for research improvement machining conditions alloy. This article devoted to systematization generalization accumulated experience at turning operation. T...
