What Is Ductile Brittle Transition Temperature?
What Is Ductile Brittle Transition Temperature? The ductile–brittle transition temperature (DBTT) is the temperature at which the fracture energy passes below a predetermined value (e.g., 40 J for a standard Charpy impact test). Ductility is an essential requirement for steels used in the construction of reactor components, such as the reactor vessel. What is the
