S. Brochard, Auteur ; P. Hirel, Auteur ; L. Pizzagalli, Auteur |

Dans Acta materialia (Vol. 58 N° 12, Juillet 2010)

The influences of surface step state and temperature on the elastic limit for dislocation nucleation from a surface step were analyzed by means of atomic scale simulations in face-centered cubic metals. When varying the step height, two regimes [...]
