Investigation of the elementary mechanisms controlling dislocation / twin boundary interactions in fcc metals and alloys : from conventional to advanced TEM characterization

The elementary mechanisms controlling the interactions between lattice gliding dislocations and twin boundaries were carefully analyzed using conventional and advanced transmission electron microscopy techniques in both bulk coarsegrained Fe-Mn-C TWIP steels with deformation twins and nanocrystalline Palladium thin films with nanoscale growth twins.
