| Abstract Scope |
The advent of additive manufacturing (AM) has enabled the development of functionally graded materials (FGMs), which offer tailored properties by gradually varying material composition within a single part. Such materials provide innovative solutions for applications involving dissimilar material joints or location-specific property requirements.
This study explores the design and fabrication of FGMs transitioning from stainless steel 316L to Ni-based superalloy IN718 using direct energy deposition (DED). A dual approach is undertaken, combining: (1) advanced characterization methods, including SEM, EDX, EBSD, XRD, and hardness testing, to evaluate microstructure and mechanical properties; and (2) computational thermodynamics (CalPhaD) to analyze phase stability and thermal behavior across the gradient.
The investigation aims to understand mechanisms of microstructure selection, defect formation (e.g., micro-cracks), and phase evolution in FGMs. These insights contribute to establishing a reliable methodology for designing and processing metallic FGMs for advanced industrial applications. |
