Abstract Scope |
This presentation covers a deep learning scheme of phase recognition for steel materials. A convolutional neural network (CNN) classifier is established, such that the martensite phase, which has a substantial impact on the mechanical properties of steels, can be recognized from microstructure images and its volumetric fraction can also be estimated from multi-phase microconstituents. The testing results on an ultrahigh carbon steel dataset proved that the developed scheme has good phase recognition accuracy. The estimated martensite fraction can be used as an essential feature to predict the mechanical properties of materials in additive manufacturing. The procedures were applied to train a CNN model using H13 SEM collected from the literature and then the martensite fraction was extracted with this trained model. Subsequently, a multilayer ANN model was constructed and trained to predict the mechanical properties with 11 input elements, including the martensite fraction and the grain size area density bins. |
