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 ...

The Scientific Temper, 2022
The effect of different mineral fillers (Talc, calcium carbonate, clay, mica) on the tougheningbehavior and ductile-brittle transition temperature (DBTT) of TPOs composites has beeninvestigated in the paper. An attempt was made to investigate impact strength to determine theDBTT of the mineral-modified TPO composite system by employing a series of ...

Ductile–brittle transition temperature of polylactic acid-based biocomposite
Journal of Thermoplastic Composite Materials, 2011Almost all materials exhibit sensitivity of mechanical properties to temperature. Polylactic acid (PLA), an amorphous polymeric material, also exhibits this type of behavior. Because of its limited application in structural purpose, very few journals and articles study the ductile–brittle transition temperature (DBTT) of polymeric materials ...
