Ductile-to-brittle transition in cenosphere-filled polypropylene composites
Journal of Materials Science, 2010Cenosphere-filled polypropylene (PP) composites were fabricated and characterized for their structural/morphological and fracture mechanical behaviour. The fracture properties were studied following the essential work of fracture (EWF) approach based on post-yield fracture mechanics (PYFM) concept.

Orientation-dependent ductile-to-brittle transitions in nanostructured materials
Acta Materialia, 2008Strengths of materials close to the upper theoretical limit have been observed in a number of recent experimental studies. The dimensions of the samples have been on the micron length scale and the strength is conferred by the absence of flaws. Below a critical length scale crystalline materials can sustain stresses near the theoretical strength ...

Ductile to brittle transition in the Zr41.2Ti13.75Cu12.5Ni10Be22.5 bulk metallic glass
Intermetallics, 2006Abstract The variation of impact toughness, Γ, of a Zr41.2Ti13.75Cu12.5Ni10Be22.5 (Vitreloy-1) bulk metallic glass (BMG) within the temperature range of 123–423 K was evaluated by using an instrumented Charpy impact testing machine, in order to examine if the BMGs exhibit ductile-to-brittle transition (DBT) that is seen in rapidly quenched glasses ...

Factors affecting the shape of the ductile-to-brittle transition
International Journal of Pressure Vessels and Piping, 2002Abstract This paper uses a statistical model of cleavage fracture to examine the effect of various material parameters on the mean toughnesses of ferritic steels in the transition region. Individually, changes in the flow properties, in the effective surface energy, and in the distribution of particles from which cleavage is initiated, all affect the

Size-Scale Transition from Ductile to Brittle Failure
2021With the scientific advances of the last few decades in the field of Material Mechanics it has been realized that the traditional concept of strength, understood as force per unit surface causing fracture, is in need of revision, especially in the cases where particularly large or particularly small structures are involved. The strength of the material

Ductile-to-brittle Transition in Superplastic Silicon Nitride Ceramics
Journal of Materials Research, 2002The ductile-to-brittle transition was observed in a superplastic silicon nitride nanoceramic. This transition depends on strain rates and deformation temperatures. Generally, the material exhibits ductility at low strain rates and high deformation temperatures. At 1600 °C, the material is brittle when the strain rates are higher than 10−3/s. At a fixed

Analysis of Ductile to Brittle Transition Temperature of Stainless Steel
SSRN Electronic Journal, 2018All ferrous materials exhibit a transition from ductile to brittle when tested above and below a certain temperature, called as Transition Temperature. The Ductile-to-Brittle Transition Temperature is a phenomenon which is mainly observed in metals. Below the particular temperature the material suddenly losses its ductility and it changes from ductile ...

Comparison of ductile-to-brittle transition curve fitting approaches
International Journal of Pressure Vessels and Piping, 2012Abstract Ductile-to-brittle transition (DBT) curve fitting approaches are compared over the transition temperature range for reactor pressure vessel steels with different kinds of data, including Charpy-V notch impact energy data and fracture toughness data.

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
