Abstract Scope |
This research introduces a physics-informed generative AI framework that utilizes Latent Diffusion Models (LDMs) to predict microstructural deformation in materials by leveraging undeformed optical microscopy images alongside embedded crystallographic data. Conditioning the LDM with experimentally derived insights, our approach achieves high-fidelity predictions of critical deformation processes up to higher strain levels, capturing phenomena such as slip band evolution and grain boundary migration under uniaxial tensile loading. Through fine-tuning on high-resolution
stainless steel 316L datasets, generated via in-situ tensile testing with panoramic imaging, this work integrates physics-informed machine learning with experimentally validated material deformation modeling. By synthesizing time-sequenced data that reflects both evolving and emergent microscopic
features, this method offers a scalable, resource-efficient alternative for alloy design and testing, advancing toward next-generation materials with
tailored mechanical properties and providing rapid, predictive insights into material behavior under complex loading conditions. |
