Research on a deep learning-based automatic identification system for the fracture fibrous ratio in impact fractures of 9Ni steel
As a critical structural material for liquefied natural gas storage and transportation, 9Ni steel requires precise assessment of its impact toughness, which hinges on the accurate measurement of the fracture fibrous ratio (FFR) from impact tests—a process currently reliant on manual visual inspection that is subjective...
