Instance Segmentation of Dislocations in TEM Images
Karina Ruzaeva, Kishan Govind, Marc Legros +1
Quantitative Transmission Electron Microscopy (TEM) during in-situ straining experiment is able to reveal the motion of dislocations -- linear defects in the crystal lattice of met…
Data-mining of In-Situ TEM Experiments: on the Dynamics of Dislocations in CoCrFeMnNi Alloys
Chen Zhang, Hengxu Song, Daniela Oliveros +3
High entropy alloys are a class of materials with many significant improvements in terms of mechanical properties as compared to ``classical'' alloys. The corresponding structure-p…
Orientation-related twinning and dislocation glide in a Cantor High Entropy Alloy at room and cryogenic temperature studied by in situ TEM straining
Daniela Oliveros, Anna Fraczkiewicz, Antonin Dlouhy +4
In situ straining experiments were performed in a TEM on an equimolar CoCrFeMnNi (Cantor) high entropy alloy at room and cryogenic temperature. Perfect and partial dislocation acti…
Predicting the flow stress and dominant yielding mechanisms: analytical models based on discrete dislocation plasticity
Jianqiao Hu, Hengxu Song, Zhanli Liu +3
Dislocations are the carriers of plasticity in crystalline materials. Their collective interaction behavior is dependent on the strain rate and sample size. In small specimens, det…
Multiscale study of the dynamic friction coefficient due to asperity plowing
jianqiao Hu, Hengxu Song, Stefan Sandfeld +2
A macroscopically nominal flat surface is rough at the nanoscale level and consists of nanoasperities. Therefore, the frictional properties of the macroscale-level rough surface ar…
