Abstract Scope |
Hybrid additive manufacturing (HAM) integrates 3D printing with complementary materials fabrication techniques to enable the additive manufacturing of larger samples of complex geometries. The overall performance of the hybrid manufactured product is often influenced by the integrity of the interface between the substrate and the built part. Al-Si10-Mg and Al-Si7-Mg powders were separately printed at standard selective laser melting parameters unto cold rolled 6061, 6082 and 5083 alloys. SEM/EDS mapping, and X-Ray diffraction analyses revealed useful information on the metallurgical interactions occurring at the interfaces. These amongst others, include metal deportment phenomena, microstructural inhomogeneities and phase distribution. Nanoindentation studies across the substrate-interface-built regions validated the correlated hardness and strength properties with the gradients in the structural features |
