| Abstract Scope |
Powder-blown laser directed energy deposition (DED) facilitates the flexible fabrication of functionally graded materials (FGM), which enables parts with the optimal spatial distribution of materials and process conditions for a precisely tailored mechanical response. However, the dearth of design-ready material properties of mixed materials and the high degree of design freedom in DED printing parameters limit the rapid adoption of FGMs. Motivated by our recent investigation exploring the properties of a mixed 316L-Si and FerriumŪ PH48S stainless steel FGM, in which we found a nonlinear correlation between the mixture percentage and the mechanical response, we propose a detailed framework for determining the process-structure-property relations across the DED process envelope for mixed alloy systems. Furthermore, we integrate feedback control inputs from in-situ measurement signals to improve printing consistency. This work paves the way for the co-design of manufacturing processes and materials for high-performance applications. |
