Abstract Scope |
Advanced manufacturing research and development is typically undertaken on small scales, owing to the expense of experiments and nascent development of physical simulations for these novel processes. Deep learning has been used to model visually plausible microstructures but has not been used to understand how microstructures are affected by heat treatment. We propose to address this gap by using invertible neural networks to holistically model the effects of heat treatment, e.g., tempering. We apply the developed model to SEM imagery from shear-assisted processing and extrusion manufacturing. We find that this approach produces preserves information regarding a sample's material properties or experimental process parameters under simulated (de)tempering. We also show that topological data analysis can be used to stabilize model training and improve downstream results. We assess directions for future work and identify our approach as a step towards a holistic, end-to-end AI-enabled system for accelerating advanced manufacturing research and development. |
