Wire-arc directed energy deposition (wire-arc DED), recognized for its ability to produce large-scale parts, has gained considerable attention. However, a critical issue with this method is the high prevalence of internal porosity defects found in the manufactured aluminum components, adversely impacting their mechanical properties. For the first t...
Wire-arc additive manufacturing (WAAM) has been extensively studied thanks to its high material utilization rate and ability to form large-size components. However, due to the considerable internal porosity, the as-build (AB) parts usually exhibit poor tensile and fatigue properties. In this study, laser shock peening (LSP) was applied as a post-tr...
Laser shock peening (LSP) has been widely applied to enhance the mechanical properties of metallic materials by modifying their sub-surface microstructures. However, controversies still exist on whether grain refinement can be obtained after the LSP process. To investigate the effect caused by LSP in metallic materials, a 7050 aluminum alloy and 31...
The manufacturing sector has experienced a rapid advancement in the last few decades. From the popularization of computer numerical control machines as the face of traditional machining to the development of additive manufacturing (AM), it has been an open field in a series of innovations. Although AM is promising in terms of material savings and g...
