Microstructure-based cleavage parameters in bainitic, martensitic, and ferritic steels [PDF]

, 2023
Multi-barrier cleavage models consider cleavage fracture which is characterized by a series of microscale events. One of the challenges for multi-barrier cleavage models is the strong variations of cleavage parameters across different types of steels ...
