Brittle-to-Ductile Transition in Metallic Glass Nanowires

open access: yesNano Letters, 2016
When reducing the size of metallic glass samples down to the nanoscale regime, experimental studies on the plasticity under uniaxial tension show a wide range of failure modes ranging from brittle to ductile ones. Simulations on the deformation behavior of nanoscaled metallic glasses report an unusual extended strain softening and are not able to ...

Brittle to Ductile Transition in Intermetallic Alloys

open access: yesMRS Proceedings, 2002
ABSTRACTTwo distinct approaches are commonly invoked to explain the brittle to ductile transition of a material in the presence of a crack. In one approach, dislocation mobility plays the key role. In the other approach, the competition between crack tip dislocation nucleation and cleavage failure plays the key role.

Brittle-to-Ductile Transition of Sulfonated Polystyrene Ionomers

ACS Macro Letters, 2021
This study examines the brittle-to-ductile transition of sulfonated polystyrene ionomers (SPS) with different counterions. The polystyrene precursor was unentangled and had two ionic groups per chain on average. Thus, its terminal relaxation time was comparable to the lifetime of the associating ionic groups. Three types of ionomer samples were used to

The brittle‐to‐ductile transition in microlayer composites

Journal of Applied Polymer Science, 1993
AbstractThe brittle‐to‐ductile transition in continuous microlayer composites of polycarbonate (PC) and styrene–acrylonitrile copolymer (SAN) was investigated under the triaxial tensile stress state achieved at a semicircular notch. The availability of microlayer compositions with variations in the proportion of the components and also variations in ...
