Abstract Scope |
Hybrid additive manufacturing (AM) is an emerging approach to create functionally architected components based on microstructural changes, without drastically varying the material chemistry. However, methods of characterization and inspection for these components are limited to ensure they meet design requirements and are suitable for service throughout their life. It is necessary to incorporate material complexity considerations into model-based nondestructive evaluation (NDE). In this work, statistics-based ultrasonic NDE methods grounded in diffuse ultrasonic backscatter modeling are used to detect and quantify spatial variations imparted by a hybrid AM process (DED + milling). These methods were successfully implemented in self-evaluation as well as evaluation across an ensemble of Ti6Al4V samples. The results of this work are expected to inform future NDE strategies that are needed to enhance the performance of high-value components. The potential expansions and limitations of these methods are also discussed. |
