Cleavage Fracture Toughness :: Total Materia Article

The cleavage fracture of steel is generally interpreted by the weakest link mechanism which is differentiated from yielding and work hardening. The ster in the fracture toughness is therefore its most essential property. This is a principal reason of the difficulty to quantify the influence of microstructures on fracture toughness.
