Data‐driven approach to construct a fracture toughness master curve for ferritic steels based on tensile properties

The characterization of the fracture toughness (KJc) of ferritic steels in the ductile-to-brittle transition (DBT) region, which is vital for analyzing the structural integrity of cracked structures subjected to large temperature changes, has been pursued by researchers and practitioners. This is because KJc is associated with a large temperature dependence (a change of approximately 400% corresponding to a temperature change of 100°C), specimen...
