The study on force, surface integrity, tool life and chip on laser assisted machining of inconel 718 using Nd:YAG laser source
Inconel 718, a high-temperature alloy, is a promising material for high-performance aerospace gas turbine engines components. However, the machining of the alloy is difficult owing to immense shear strength, rapid work hardening rate during turning, and less thermal conductivity. Hence, like ceramics and composites, the machining of this alloy is considered as difficult-to-turn materials. Laser...
متن کاملMICROSTRUCTURAL STUDIES ON LASER WELDING OF INCONEL 718 TO 2304 DUPLEX STAINLESS STEEL WITH A FOCUS ON OPTIMAZING PROCESS PARAMETERS AND ACHIEVING THE MAXIMUM FRACTURE STRENGTH
In this research, microstructure and mechanical properties of laser welded joints between 2304 duplex stainless steel and Inconel 718 nickel-based super alloy were investigated. Microstructural evolution in the various areas of welded joints and also the effect of welding parameters on the mechanical properties of dissimilar joints were studied. Response surface methodology based on the central...
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 کاملDevelopment and Characterization of a Metal Injection Molding Bio Sourced Inconel 718 Feedstock Based on Polyhydroxyalkanoates
The binder plays the most important role in the metal injection molding (MIM) process. It provides fluidity of the feedstock mixture and adhesion of the powder to keep the molded shape during injection molding. The binder must provide strength and cohesion for the molded part and must be easy to remove from the molded part. Moreover, it must be recyclable, environmentally friendly and economica...
متن کاملLaser-assisted machining of Inconel 718 with carbide and ceramic inserts
The use of high strength materials, like titanium alloys and tool steels, is becoming increasingly common in industry. However, these materials are difficult to machine because they maintain their mechanical properties even at high temperatures. Hence, conventional machining (CM) of these materials is slow and inefficient because only slow cutting speeds can be used. In order to increase produc...
