The effect of pre-deformation on nanoscale precipitates and hardness a maraging stainless steel strengthened by the co-precipitation Ni3Ti, Mo-enriched Cr-enriched was systematically studied using electron back scattered diffraction, transmission microscopy atom probe tomography (APT). Hardness measurements showed that specimen with deformation ratio 90% peaked at HV 718 aged for 24 h, which is...

Maraging steels such as 18Ni-300 (1.2709) are characterized by high yield and tensile strength together with good toughness making them interesting materials for aerospace, automotive tooling sectors well bearing gears parts. The low carbon martensite matrix combined the nanosized intermetallic precipitates responsible peculiar mechanical properties. Thanks to very content, these easily weldabl...

Bulk phase transformations and dislocation density were monitored in a maraging stainless steel on bulk level using in-situ neutron diffraction up to 1340 °C, i.e. 30 °C below the melting temperature. Three materials with different initial microstructure and/or composition studied: wrought, as-built SLM-ed (selective laser melted) re-austenitized SLM-ed. In contrast wrought martensitic steel, w...
