Abstract Scope |
The 6xxx series aluminum alloys feature high-strength, excellent conductivity, and corrosion resistance. They are favored for bridges, high-speed ships, and offshore constructions mainly due to their superior corrosion resistance in saltwater, thanks to a thin oxide layer formation on their surface. Al6061 alloy, in particular, shows better coating adhesion in marine environments. The advent of advanced additive manufacturing processes offers a chance to design components with less material wastage, moving towards near-net shapes. In this investigation, we deposited a thin wall (150 mm ×150 mm) using robotic wire arc AM process leveraging a custom fabricated nanoparticle treated Al6061 wire. Post fabrication, metallography and tensile specimens were extracted to establish the process-microstructure-property relationship of test samples as a function of build height. Additionally, the evolution of residual stress along the build direction was captured to develop strategies which can avoid distortion in large scale AM parts fabricated from Al6061 alloy. |
