Abstract Scope |
Small-punch creep (SPC) testing is currently used to evaluate the creep-rupture properties of steels used in the petrochemical industry. This study explores processing-microstructure-property relationships in service-exposed C-Mn steels using machine learning (ML). These reduced order models can be used to rank the different microstructural features in terms of their importance on the SPC-test and potentially be used to prioritize/reduce SPC testing requirements. A dataset consisting of 120 steel microstructures and their associated mechanical properties were collected. Large area mapping using secondary electron imaging of the etched surfaces yielded high-resolution data of the ferrite/pearlite phases in the C-Mn steels. These images were segmented and quantified using various traditional and deep-learning feature extraction methods, which were then used as inputs for training regression models using different ML techniques. The use of microstructure-property databases for microstructural-based remnant life assessments of high-temperature components will also be discussed. |
