Constraint Effect on Fracture in Ductile-Brittle Transition Temperature Region
Volume 1: Codes and Standards, 2021Abstract Bend fracture tests using flat plate specimens of 50mm thickness with a surface crack, 1TC(T), and SE(B) specimens of low alloy steel were performed in the ductile-brittle transition temperature (DBTT) region. Two types of SE(B) specimen, a/W = 0.1 and 0.5, were used.

Statistical method of determining ductile-brittle transition temperature
Metal Science and Heat Treatment, 19731. By physical nature the critical brittleness temperature is a random variable and can be represented by the statistical distribution. 2. For steel 20L the type of fracture is a more accurate criterion for determining Tcri than the impact strength, and the standard deviation of % D increases sharply in the critical temperature range ...

Ductile-brittle transition in steels at near-solidus temperatures
Metal Science and Heat Treatment, 2006A complex study of the nature of the little-investigated phenomenon of high-temperature brittleness of steels, i.e., the ductile-brittle transition observed in the temperature range t = (0.92–0.98)tmelt, is described. Regular features in the behavior of mechanical properties of low-alloy steels in this temperature range are considered.
