| Abstract Scope |
This research investigates the additive friction stir deposition (AFSD) of Inconel 625 (IN625), a nickel-based superalloy, focusing on the effects of processing parameters on mechanical performance. AFSD involves complex thermo-mechanical processes such as frictional heating, plastic deformation, and viscoplastic material flow which may vary with the deposition process parameters. The study examines key parameters such as tool rotation speed, traverse speed, and deposition temperature, analyzing their influence on microstructure and mechanical properties. Miniature tensile testing was employed to compare the mechanical behavior of AFSD and wrought alloys, while electron backscatter diffraction was used for detailed microstructural analysis. The results reveal that optimizing these parameters leads to an improved microstructure, fewer defects, and better mechanical performance. Specifically, the tensile strength and hardness of IN625 are significantly influenced by the chosen processing parameters. This research offers critical insights into optimizing AFSD processes for IN625, highlighting its potential for high-performance applications. |
