| Abstract Scope |
Additive manufacturing(AM) offers significant advantages, including design flexibility and reduced production times. However, qualifying AM parts remains challenging due to complex thermal histories that result in heterogeneous microstructures and location-dependent mechanical properties. These complexities render traditional testing methods costly and time intensive. To address these challenges, this study investigates the mechanical behavior of SS 316L components fabricated using the Directed Energy Deposition method. Small tensile specimens, each measuring 3 mm × 1.2 mm × 0.25 mm, were extracted from various regions of an AM part to assess stiffness, yield strength, tensile strength, and strain-to-failure. This methodology provides direct insight into spatial variations in mechanical performance, linked to thermal conditions during manufacturing. Additionally, it enables identification of critical regions and supports the development of a finite element model for predicting part lifespan. Overall, this approach advances understanding of spatial heterogeneity in AM parts and establishes a foundation for improved performance assessment. |
