In this work, molecular dynamics (MD) simulations were used to investigate elementary dislocation properties in a Co-free high entropy (HEA) model alloy ($Cr_{15}Fe_{46}Mn_{17}Ni_{22}$ at. %) in comparison with a model alloy representative of Austeni

The flow stress in irradiated Austenitic Stainless Steels (ASSs) is analyzed in terms of the microstructure features and the fundamental mechanisms of plastic deformation. A set of constitutive equations is proposed to assess the contributions of dis

Ageing of cast duplex stainless steels (DSS) is attributed to the decomposition of the ferrite: spinodal decomposition and precipitation of G-phase particles. This leads to an increase in hardness and a decrease in Charpy toughness. According to the

3D -DD simulations are performed with cubic grains ranging from 1 to 10 μm to investigate the physical mechanisms at the origin of the Hall- Petch law. In particular, the long-range stress (back stress) induced by the density of polarized dislocatio

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, three orientations (, and ) and three shapes (cube, plate and nee

Reactor pressure vessel steels are well-known to harden and embrittle under neutron irradiation. The primary mechanism of radiation embrittlement for these bainitic steels is the obstruction of dislocation motion, mainly due to clusters or precipitat
