Fast high-temperature consolidation a novel way to understand the microstructural heterogeneities in nano-reinforced ferritic steels

Abstract : Oxide-Dispersion Strengthened (ODS) ferritic steels were produced by powder metallurgy using a field-assisted sintering technique called spark plasma sintering (SPS). A multiscale characterization using electron microscopy combined with an in situ synchrotron X-Ray Diffraction allowed to understand the evolution of the heterogeneous microstructure. The influence of oxides precipitation was quantified by nanoscale observations to explain the microstructure heterogeneities in ferritic ODS alloys.
