Unsupervised Machine-Learning Pipeline for Data-Driven Defect Detection and Characterisation: Application to Displacement Cascades

Samuel Del Fré, Andrée de Backer, Christophe Domain +2

Neutron irradiation produces, within a few picoseconds, displacement cascades that are sequences of atomic collisions generating point and extended defects which subsequently affec…

The impact of alloying elements on the precipitation stability and kinetics in iron based alloys: An atomistic study

Giovanni Bonny, Christophe Domain, Nicolas Castin +2

Iron based industrial steels typically contain a large number of alloying elements, even so-called low alloyed steels. Under irradiation, these alloying elements form clusters that…

Elastic dipole tensors and relaxation volumes of point defects in concentrated random magnetic Fe-Cr alloys

Jan S. Wróbel, Marcin R. Zemła, Duc Nguyen-Manh +5

Point defects in body-centred cubic Fe, Cr and concentrated random magnetic Fe-Cr are investigated using density functional theory and theory of elasticity. The volume of a substit…

Validity of crystal plasticity models near grain boundaries: a contribution of elastic strain measurements at the micron scale

Emeric Plancher, Pouya Tajdary, Thierry Auger +8

Synchrotron Laue microdiffraction and Digital Image Correlation measurements were coupled to track the elastic strain field (or stress field) and the total strain field near a gene…

Effects of the grain size and shape on the flow stress: A dislocation dynamics study

Maoyuan Jiang, Benoit Devincre, Ghiath Monnet

Dislocation dynamics simulation is used to investigate the effect of grain size and grain shape on the flow stress in model copper grains. We consider grains of 1.25-10 m size,…
