Abstract Scope |
Functionally graded materials (FGMs) are engineered composites designed with optimized properties, enabling enhanced performance even within a single component. In this study, two Iconnel/Copper FGMs systems were fabricated using Directed Energy Deposition (DED) with a blue laser. This combined technology enables the building of radially and longitudinally controlled gradients for each system produced. This investigation demonstrates an effective method for improving thermal and mechanical properties, addressing problems such as the stress that arises due to differences in thermal expansion coefficients between two metal materials and localized stress concentrations. The two bimetallic systems were characterized using X-ray Fluorescence (XRF), CT scanning, Energy-dispersive X-ray spectroscopy (EDS), and thermal conductivity analysis. The novel material combination and the system geometry are critical for applications in aerospace, defense, energy, and advanced manufacturing sectors, where building systems with dissimilar materials in a single structure is crucial for optimal operation and durability. |
