Atom probe tomography is recognised as a key technique for exploring materials down to the subnanometer scale. Among the many systems studied since the late 1960’, iron-chromium has received a continuous attention. Because of its ablity to detect iron and chromium composition fluctuation,combined with its mass and spatial resolutions, atom probe is the ideal technique for investigating this system. Fe-Cr exhibit a fundamental interest, as one of the only systems showing isotropic spinodal decomposion over a large range of composition and temperatures. For this reason, and for industrial reasons (in particular because of the so called 475°C embrittlement phenomenon in ferritic and martensitic stainless steels), it has been extensively investigated as a model system for studiying this phase transformation mechanism, in particular by the Oxford group under the guidance of G. Smith. Some of the early and more recent results on this system will be presented in this contribution.
