報告摘要:The unique flexibilities of additive manufacturing (AM) to build complex-geometry components have been well investigated. However, the potential in AM of metallic components with high complexity in material distribution lacks exploration. Current AM of multi-materials are mostly in a linear format, which hardly inherit the merits of constitutive materials effectively and have demonstrated anisotropic mechanical properties. Laser additive manufacturing (LAM) enables the processing of heterogeneous materials with customised architectures to combine the merits of constitutive materials for attaining better mechanical property and functionality. To fully leverage the material-complexity capability of LAM, this report will introduce multi-type heterostructured multi-materials with configurable architectures from 1D to 3D, which includes the LAM-processed unidirectional, layerwise and voxelised heterostructured materials. The microstructure evolutions, interfacial bonding mechanisms, localised deformation behaviour, multi-scale mechanical properties and underlying strengthening mechanisms will be elucidated. The findings demonstrated a novel approach to circumvent material property tradeoffs. Furthermore, the findings could stimulate a promising research domain by AM of functional components with the configurable distribution of multiple materials in multi-scales for superior performance and novel functionality.
