| Abstract Scope |
The development of advanced materials with gradual compositional changes is essential for applications requiring tailored properties. This study explores the fabrication of Functionally Graded Materials (FGMs) and Bimetallics using Directed Energy Deposition (DED) technology with two types of metal powders, C103(Nb based Alloy) and Ti-6Al-4V(Ti based Alloy). By systematically varying the composition across layers, FGM samples were produced, with material ratios changing by 10% per layer. Microstructural analysis using a Scanning Electron Microscope (SEM) confirmed successful FGM production without delamination or cracks. Energy Dispersive X-ray Spectroscopy (EDS) analysis revealed continuous compositional changes across 11 steps. And the rocket nozzle extension was manufactured using combination of two materials. This research demonstrates that DED-based FGM production using the C103 alloy has potential utility in aerospace product design and manufacturing. Future research will focus on a detailed analysis of the properties and optimization of the FGM production process. |
