| Abstract Scope |
Wire and Arc Additive Manufacturing (WAAM) offers a high deposition rate leading to the capability to manufacture large components with lower cost. Age hardened aluminium alloys are widely used for structural applications because of their high specific properties. Recent development of a Metal Inert Gas deposition process based on a low-energy short-circuit transfer mode, called Cold Metal Transfer //174; made the use of these poorly weldable alloys, such as age hardened 6061 aluminium alloy, possible by WAAM. Microstructures and nanostructures are strongly influenced by the main process parameters and do have a critical influence on the mechanical performances of the built part. To date, no detailed studies on the precipitation hardening in aluminium parts achieved by WAAM are available, especially as regard to Al-Mg-Si alloys. Therefore, the present work aims to relate the relationship between microstructural features and mechanical properties in such a WAAM additively manufactured alloy. |
