Interaction between dislocations and oxide precipitates in an aluminium containing ferritic stainless steel

Ferritic and martensitic steels strengthened by oxide dispersion (ODS) are studied at the nanometre scale because the interaction between dislocations and nanosized precipitates drives mechanical behaviour and evolution during neutron irradiation. Observation by Analytical Electron Microscopy (AEM) aside chemical information brings information about the coherency of precipitates, their strain field and the surrounding dislocations.
