An arbitrarily defined temperature that lies within the temperature range in which metal fracture characteristics change rapidly, such as the ductile-to-brittle transition temperature (DBTT). The DBTT can be assessed in several ways, the most common being the temperature for 50% ductile and 50% brittle fracture, or the lowest temperature at which the fracture is 100% ductile.
