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...

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

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 ...

The segregation of Alloy 718 ingots and the technical factors which affect the ingot homogenization practice are studied in this paper. The segregation and melting point of Alloy 7 18 ingots are studied by DTA, electron microprobe and structure analysis. The elimination of Laves phase is studied in detail. After the solution of Iaves phase the segregation elimination of Nb is reviewed further. ...

A variety of cast pyrometR 718 alloy microstructures result from processing of different diameters of industrial scale ingots for producing superalloy forgings used in aircraft turbine engine applications. The hot workability of these cast alloys will significantly depend on the cast microstructure. The current study is focussed on understanding the evolution of the cast microstructure during V...
