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...

In this work, authors had made computer FEM (finite element method) simulation of machining holes in part heat-resistant alloy Inconel 718. For nonlinear solver LS – Dyna been used. Material type for physical modeling workpiece have selected to Johnson Cook formulation. Tool configuration is rigid and dynamic stiffness three dimensions the fastening points. Graphs cutting forces moments differe...
