Abstract Scope |
Designing materials to meet specific demands is essential in materials science, requiring a deep understanding of the process-structure-property (PSP) relationship. Traditional methods rely on feature engineering, while deep learning offers a framework that eliminates this need and enhances performance. This study introduces a deep learning framework to establish the PSP linkage for the heat treatment, microstructures, and mechanical properties of 42CrMo4 steel. We employed a conditional StyleGAN to generate microstructure images based on tempering temperatures and a ResNet algorithm to predict yield strength, tensile strength, and elongation from these images. Samples were heat-treated at various temperatures, revealing that lower temperatures resulted in tempered martensite, while higher temperatures increased ferrite content. Strength values decreased with rising tempering temperatures for both observed and generated images. The ResNet predictions aligned well with actual measurements, demonstrating the framework's ability to generate plausible microstructures and accurately predict properties under new conditions. |
