Prediction of Fracture Toughness of Steels According to the Microstructure and Chemical Composition

Article Preview

Abstract:

The influence of microstructure parameters and chemical composition on the fracture toughness of steel is investigated. It is shown that the crack resistance of steel can not be reliably estimated only by a single parameter of the microstructure or only by chemical composition. A generalized parameter of microstructure and chemical composition, which correlates well with crack resistance, is proposed.
