Abstract Scope |
Wire-feed direct energy deposition (WFDED) is an up-and-coming AM method because of its high deposition rates and flexible application. However, operating parameters in WFDED are not independent and the microstructure of the as-built part is hard to predict. To extend its application, it is crucial to find a way to predict the microstructure of as-built parts. In this work, we analyzed both Ti-6Al-4V single-bead and stacked-bead samples made with various power levels and speeds. Moreover, microstructure characterization and hardness measurements are correlated with the operating parameters. Multiple informatics methods are applied to the dataset to map the < process | microstructure | properties > relationships for better control of final microstructure/properties. The analysis provides insights into the scope of data analytics methods for quantifying process uncertainty. |
