On the ductile-to-brittle transition temperature in MoSi2
Scripta Metallurgica et Materialia, 1992This paper reports that the intermetallic compound MoSi[sub 2] combines excellent oxidation resistance, a high melting point (2020[degrees]C), reasonable strength and density, and good thermal conductivity, making it a promising material for structural applications above 1200[degrees]C.

The ductile to brittle transition in tin-lead alloys near melting temperatures
Metallurgical Transactions A, 1983Tensile tests were carried out on tin containing up to 2.0 wt pct lead between 160 and 220 °C at strain rates of 8.3 x 10-3 and 8.3 x 10-4 s-1. Both as-cast and heavily deformed samples were examined. The samples exhibited a ductile-brittle transition at a temperatureTDB below the equilibrium solidus temperature of the corresponding alloy.TDB was found

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.

Materials Science and Engineering: A, 2011
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 ...

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

Competing risks models for fracture in the ductile to brittle transition temperature region
International Journal of Fracture, 1995When fracture toughness testing is carried out over the ductile to brittle transition temperature region cleavage instability may be observed at the initiation of cracking or after some prior ductile crack growth. The amount of precleavage ductile crack growth increases with increasing temperature.

Correlation of Magnetic Properties and Ductile-to-Brittle Transition Temperature in Pipelines
Key Engineering Materials, 2014Drop-weight tear tests were conducted on high toughness pipeline steel, in order to analyze by fractography study the fracture appearance, occurring in the region impacted by a hammer. Measurements of hysteresis loops, in a range of very low temperatures (-20°C to-60°C), have been performed on samples in order to correlate its magnetic properties with ...

Effect of specimen geometry on impact strength and ductile-to-brittle transition temperature
Soviet Materials Science, 1972Data on the effect of specimen geometry on the ductile-to-brittle transition temperature of low-alloy steel are reported. The influence of the cross-sectional area, specimen width and thickness, notch angle, and root radius were studied.

The influence of competing fracture mode on the ductile to brittle transition temperature
Engineering Fracture Mechanics, 1993Abstract The influence of competition between the fracture modes in the ductile to brittle transition region of structural steels on their measured fracture probability density functions (PDF) is considered and analysed. Such competition is shown to shift and distort measured PDFs from true PDFs.

Journal of Polymer Science Part B: Polymer Physics, 2019
ABSTRACTThe temperature dependence of the ballistic impact performance of a series of transparent polymer networks is evaluated. A systematic series of homogeneous epoxy/propylene‐oxide‐based thermosets, a nanoscale phase‐separated epoxy/dual amine thermoset, and two homogeneous, completely aliphatic materials synthesized via ring‐opening metathesis ...
