Application of bulk deformation methods for microstructural and material property improvement and residual stress and distortion control in additively manufactured components

Colegrove, Paul A.; Donoghue, J.; Martina, Filomeno; Gu, Jianglong; Prangnell, P. B.; Honnige, Jan (Elsevier, 2016-11-08)

Many additively manufactured (AM) materials have properties that are inferior to their wrought counterparts, which impedes industrial implementation of the technology. Bulk deformation methods, such as rolling, applied ...
Deformation microstructures and strengthening mechanisms for the wire+arc additively manufactured Al-Mg4.5Mn alloy with inter-layer rolling

Gu, Jianglong; Wang, Xiaoshu; Bai, Jing; Ding, Jialuo; Williams, Stewart W.; Zhai, Yuchun; Liu, Kun (Elsevier, 2017-11-29)

Applying inter-layer rolling to the wire+arc additively manufacturing (WAAM) process with increasing loads of 15 kN, 30 kN and 45 kN, achieves excellent mechanical properties for 5087 (Al-Mg4.5-Mn) alloys. Compared with ...
Micropore evolution in additively manufactured aluminum alloys under heat treatment and inter-layer rolling

Gu, Jianglong; Yang, Shouliang; Gao, Minjie; Bai, Jing; Zhai, Yuchun; Ding, Jialuo (Elsevier, 2019-10-28)

The application of wire + arc additively manufactured (WAAM) aluminum alloys has been restricted by the porosity defect, which is generally detrimental to the mechanical properties. Suppressing of micropores in the WAAM ...
Microstructure, defects, and mechanical properties of wire + arc additively manufactured AlCu4.3-Mg1.5 alloy

Gu, Jianglong; Gao, Minjie; Yang, Shouliang; Bai, Jing; Zhai, Yuchun; Ding, Jialuo (Elsevier, 2019-11-13)

The wire with a composition of AlCu4.3%Mg1.5% was customized and used to deposit the WAAM alloy with the power source of cold metal transfer. The microstructure, defect, and mechanical properties of the as-deposited and ...
The strengthening effect of inter-layer cold working and post-deposition heat treatment on the additively manufactured Al-6.3Cu alloy

Gu, Jianglong; Ding, Jialuo; Williams, Stewart W.; Gu, Huimin; Bai, Jing; Zhai, Yuchun; Ma, Peihua (Elsevier, 2015-10-26)

Wire + Arc Additive Manufacture (WAAM) attracts great interest from the aerospace industry for producing components with aluminum alloys, particularly Al-Cu alloy of the 2000 series such as 2219 alloy. However the application ...
