Microstructure Evolution of Al6061 Alloy Made by Additive Friction Stir Deposition. [PDF]

Materials (Basel), 2022
In this paper, the phase structure, composition distribution, grain morphology, and hardness of Al6061 alloy samples made with additive friction stir deposition (AFS-D) were examined. A nearly symmetrical layer-by-layer structure was observed in the cross section (vertical with respect to the fabrication-tool traversing direction) of the as-deposited ...

In-Situ Monitoring and Control of Additive Friction Stir Deposition. [PDF]

Materials (Basel)
Additive friction stir deposition (AFSD) is a solid-state AM method that feeds, plasticizes, and deposits solid bars using frictional heat. Although the AFSD is a promising method, its limited technology readiness level precludes its wider use. The use of optimum process parameters is critical for achieving successful results, and closed-loop control ...
