Additive manufacturing (AM) of aluminum alloy components has drawn broad attention from industrial customers in recent years. With the advantages of low cost and high deposition rate, wire + arc additive manufacturing (WAAM) has been recognized as a promising AM technology in producing large-scale aluminum alloy structural parts. However, the adverse effect of internal defects on mechanical properties has limited the application of WAAM aluminum alloys. Micropores, as one of the most harmful defects, are normally detrimental to the fatigue, strength, and toughness of aluminum alloys. […] Suppressing of micropores in the WAAM components has attracted considerable attention in recent years. […] The hybrid technique of WAAM + rolling + heat treatment has great potential in promoting mechanical properties of WAAM alloys. The results will provide a theoretical guidance for the design of high-performance WAAM aluminum alloy components.
The commercial software Avizo was employed to segment micropores information based on 2048 slice images. All the micropores were eventually re-built and labeled as 3D images. The volume and surface area of each micropore were measured and calculated by the Marching Cubes method.
