| Abstract Scope |
Additive Manufacturing (AM) is crucial for Industry 4.0 where automation and real-time decision-making are to be performed with minimal human intervention. Most AM techniques involve melting metal powders layer-by-layer to build components which allows for complex geometries to be achieved; however, one significant challenge that inhibits it from becoming mainstream is the porosity produced in the specimens. Such pores cause deterioration of the mechanical properties of the components. Moreover, such AM techniques also induce anisotropy and heterogeneity in the components with respect to the microstructure, mechanical properties, and crystallographic texture. Such problems could be overcome if AM is performed without melting. In this regard, additive friction stir deposition (AFSD) exhibits the highest potential for industrialization. AFSD involves extruding a solid metal feedstock bar layer-by-layer while being heated by a rotating tool. In this work, the microstructure and mechanical behavior of Al 6082 alloy after AFSD have been investigated. |
