A comparative study of additively manufactured thin wall and block structure with Al-6.3% Cu alloy using cold metal transfer process (2017, methodology): “3%Cu alloy was also studied with the cold metal transfer (CMT) process [13], with a focus of the effect of inter-layer cold working and post-deposition heat treatment on the material strengthening of this alloy [8] and their effect on porosity control [14].”
Design for Additive Manufacturing (2019, background): “aluminium alloys during Wire + Arc Additive Manufacturing (WAAM) reduces porosity [136] and increases strength due to finer sub-grains and fewer mis-orientations [137].”
Deformation microstructures and strengthening mechanisms for the wire+arc additively manufactured Al-Mg4.5Mn alloy with inter-layer rolling (2018, methodology): “One is that the number and size of black round-shaped pores are gradually reduced under increasing rolling loads, reasons of which were explained in a previous study by the authors [23].”
Microstructural evolution and mechanical properties of maraging steel produced by wire + arc additive manufacture process (2017, background): “Furthermore, the filler wire is one of the main sources of inclusions, nitrogen and oxygen; in the arc, inclusions can be vaporized and atomized to provide N and O to the weld pool and new inclusions will form through metallurgical reactions [2].”
An overview of wire arc additive manufacturing (WAAM) in shipbuilding industry (2020, background): “Porosity of WAAM 5087 aluminium alloy (a) as-deposited without rolling (b)–(d) 15, 30, 45 kN inter-layer rolled (Gu et al. 2016).”
Control of residual stress and distortion in aluminium wire + arc additive manufacture with rolling (2018, background): “- 5 are therefore not comparable, but consistent with the respective references for vertical rolling [39] and side rolling [14] 2.”
A review of wire arc additive manufacturing and advances in wire arc additive manufacturing of aluminium (2018, background): “able density of dislocations remains induced [59] in the interlayer rolled object favouring the tensile strength increment.”
