Effect of specimen size in determining ductile to brittle transition temperature
Materials Science and Technology, 2015Ductile to brittle transition temperature (DBTT) for 9Cr–1Mo steel has been determined from Charpy impact testing for full size and subsized specimens. DBTT was obtained at various percentage of upper shelf energy (USE). Assuming that most of the energy is spent in crack initiation, notch root volumes of subsized specimens ( VNS) were normalised with ...

Preparation and ductile-to-brittle transition temperature of the La-TZM alloy plates
International Journal of Refractory Metals and Hard Materials, 2015Abstract Powder metallurgy methods were utilized to prepare lanthanum-doped titanium–zirconium–molybdenum (La-TZM) and traditional TZM alloy plates. Tensile and Charpy impact tests were employed to study the room temperature and cryogenic mechanical properties of the two kinds of TZM alloys.

The ductility below the ductile-to-brittle transition temperature of the FeCrAlloy
Journal of Alloys and Compounds, 2009Abstract The ductility below the ductile-to-brittle transition temperature of the FeCrAlloy is studied by the dynamic mechanical analysis technique. The dynamic storage modulus decreases slowly first, then with the increase of the temperature, it decreases rapidly for the FeCrAlloy and the FeCrAlloy oxidized at 650 °C. The damping increases little at

Control of ductile to brittle transition temperature in ferritic pressure vessel steel
Materials Science and Technology, 2011Controlled amounts of cold work are shown to cause a minimum in the ductile to brittle transition temperature (DBTT) in a ferritic steel at a critical level of ∼1·5. Mechanical property assessments show that the hardness values exhibit the same trend.

Ductile-to-brittle transition temperature behavior of platinum-modified coatings
Materials Science and Engineering, 1987Abstract It has been reported that the addition of platinum to diffusion aluminide coatings can significantly increase the ductile-to-brittle transition temperature (DBTT) but the current database is small. Comparison of results is difficult because of the number of variables in the coating systems, their processing, the resulting coating ...

This paper attempts to predict the cleavage fracture probability for a low-alloy bainitic steel. Fractographic analysis of broken compact tension (CT) and Charpy V-notch (CVN) specimens was performed. An evolution of physical mechanisms of cleavage initiation was found: cracked-particle-induced cleavage was observed at low temperature, whereas a ...

Abstract In the present study, ductile to brittle transition temperature of functionally graded steels has been evaluated by utilizing Charpy impact specimens with crack arrester configuration. Functionally graded steels which are composed of graded ferritic and austenitic regions together with bainite or martensite layer may be fabricated by ...
