The ductile-brittle transition of some amorphous alloys

Materials Science and Engineering, 1978
Abstract The ductile-brittle transition temperature for a number of amorphous transition metal-metalloid alloys was determined and related to composition. It was found that the embrittlement temperature decreased rapidly with the addition of phosphorus to the alloys.

Theory of ductile-brittle transition in steels and iron alloys: Theory of stress dependence of the critical temperature of ductile-brittle transition

Doklady Physical Chemistry, 2008
The author deduces required dependence on the ground of consideration of thermodynamic potential at ductile-brittle transition under stresses, having assumed power dependence of coefficients on temperature. Calculated results are compared with the Moessbauer spectra observations.

The ductile‐brittle transition of low‐density polyethylene

Polymer Engineering & Science, 1980
AbstractThe impact behavior of a low‐density polyethylene was studied with an instrumented Charpy tester. A change from elastic or ductile response to brittle fracture was observed over a small temperature interval, usually within 1°C. This characteristic impact transition temperature (ITT) was highly sensitive to shallow, sharp notches.

Inverse ductile–brittle transition in metallic glasses?

Materials Science and Technology, 2015
There is evidence that metallic glasses can show increased plasticity as the temperature is lowered. This behaviour is the opposite to what would be expected from phenomena such as the ductile–brittle transition in conventional alloys. Data collected for the plasticity of different metallic–glass compositions tested at room temperature and below, and ...

THE DUCTILE-BRITTLE TRANSITION WHEN MACHINING PERSPEX

International Journal of Production Research, 1965
SUMMARY Many materials machine in either a ductile or brittle manner depending on the cutting conditions. This paper identifies the conditions which allow perspex to be machined in a ductile manner. A quantitative assessment is made of the effects of cutting speed and feed rate on the ductile-brittle transition when turning with a tool having a 30 ...
