A Finite Volume Framework for the Simulation of Additive Friction Stir Deposition
Journal of Engineering Materials and Technology, 2023Abstract In this study, a finite volume simulation framework was developed, validated, and employed for the first time in a new solid-state additive manufacturing and repair process, Additive Friction Stir Deposition (AFSD). The open-source computational fluid dynamics (CFD) code openfoam was used to simulate the deposition of a single ...

Additive Manufacturing of Aluminum Using Friction Stir Deposition
2020In the current work, additive manufacturing process using friction stir deposition technique from die-cast Al–Si bar of 20 mm diameter against aluminum substrate was carried out. The effect of the spindle rotation speed (1200 rpm) and the feeding speed (3–5 mm/min) on the deposition process, the microstructure, and the hardness of the friction ...

A New Method for Upcycling Machining Chips for Additive Friction Stir Deposition
Additive friction stir deposition (AFSD) uses a rotating tool to generate frictional heat and plastic deformation, allowing metals to be deposited layer by layer onto a substrate without melting. This solid-state process offers an opportunity for upcycling metallic chips collected from machining operations to produce feedstock rods.Baruah, S. +4 more
