Metallurgical Factors Influencing the Machinability of Inconel 718 John J. Schirra, Pratt & Whitney
Because of the large volume of Inconel 718 used by the aerospace and power generation industries and the high percentage of metal removed to machine complex component geometries; understanding and improving the machining characteristics of Inconel 718 would result in substantial cost savings. While progress has been made in developing improved tool materials and machining processes, a detailed ...
متن کاملEvaluation of Tool Performance With Nanocrystalline Multilayer Coatings on the Machinability of Superalloy Inconel 718
In this paper, the performance of the cutting tool with nanocrystalline multilayer coatings (TiN+TiAlN) for machining of superalloy Inconel 718 in the dry and wet conditions was studied. The multi layer TiN and TiAlN with nanocrystalline structure was applied by physical vapor deposition technique (arc evaporation) on the WC-Co inserts. The results of the ball on disc wear test and the machinin...
متن کاملAn Application of Computational Intelligence Technique for Predicting Surface Roughness in End Milling of Inconel-718
In this paper, an attempt has been made to design an computational intelligence technique based expert system using Adaptive Neuro-Fuzzy Inference System (ANFIS) for predicting surface roughness in end milling of Inconel 718. Two different types of membership functions are adopted for analysis in ANFIS training and compared their differences regarding the accuracy rate of the surface roughness ...
متن کاملConstitutive and fatigue crack propagation behaviour of Inconel 718
In this licentiate thesis the work done in the TURBO POWER project Influence of high temperature hold times on the fatigue life of nickel-based superalloys will be presented. The overall objective of this project is to develop and evaluate tools for designing against fatigue in gas turbine applications, with special focus on the nickel-based superalloy Inconel 718. Firstly, the constitutive beh...
متن کاملMicrostructure-sensitive flow stress modeling for force prediction in laser assisted milling of Inconel 718
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...
