What Does DBTT Stand For?

DBTT stands for Ductile To Brittle Transition Temperature

DBTT, or Ductile To Brittle Transition Temperature, refers to the specific temperature at which a material transitions from a ductile state, characterized by significant plastic deformation before fracture, to a brittle state, where it exhibits little to no plastic deformation and fractures easily. This critical parameter is essential in materials science and engineering, particularly for assessing the impact toughness of metals and ensuring structural integrity in various applications under varying temperature conditions. Understanding DBTT helps in selecting appropriate materials for environments where temperature fluctuations may affect performance and safety.
