Electron microscopy study of the nanocrystalline precipitates in a 12Cr-9Ni-4Mo-2Cu maraging steel

Abstract:: The precipitation processes in a new type of age-hardenable maraging steel, Sandvik 1RK91, have been investigated using energy filtered transmission electron microscopy, high resolution electron microscopy and selected area electron diffraction techniques. EELS elemental mapping has allowed the sizes, spatial distributions, number densities and the formation sequences of different types of precipitates, including Cu-rich precipitates with the 9R structure, omega-Fe7Mo2 and eta-Ni-3(Ti, Mo), to be revealed with high spatial resolution. Elemental maps reveal that Ni-rich particles tend to form adjacent to existing copper-rich precipitates. These observations provide insight into the hardening mechanism of the steel during ageing.
