Gradient nano-grained (GNG) metals have shown a better strength-ductility combination
compared to their homogeneous counterparts. In this paper, the mechanical properties and …

In this study, the effects of grain size and dislocation source properties on the yield stress of
ultrafine-grained (UFG) polycrystals were examined using three-dimensional multiscale …

Проблема построения конститутивных моделей, позволяющих описывать поведение
материалов в широких диапазонах изменения параметров воздействия (температур …

Deformation twinning is an essential plastic deformation mechanism that realizes the trade–
off between strength and ductility. Twins nucleate and grow by the coordinated slip of partial …

Refractory multi-element alloys (RMEA) with body-centered cubic (bcc) structure have been
the subject of much research over the last decade due to their high potential as candidate …

Nanoindentation is a convenient method to investigate the mechanical properties of
materials on small scales by utilizing low loads and small indentation depths. However, the …

A new computational methodology for 3-dimensional (3D) Discrete Dislocation Dynamics
(DDD) in barrier-strengthened materials is developed. We couple the discrete 3D DDD …

This papers presents recent progress with materials investigations via in situ mechanical
testing at the synchrotron, so called 4D experiments. More automated and more integrated …

A mesoscale dislocation dynamics model which couples three-dimensional dislocation
dynamics (DD), and finite element method (FEM) was used to investigate the mechanical …
