  1. 1. Experimental study of phase separation in Fe-Cr based alloys

    Författare :Jing Zhou; John Ågren; Joakim Odqvist; Peter Hedström; Andersson Marcus; KTH; []
    Nyckelord :Duplex stainless steels; Ferritic stainless steels; Spinodal decomposition; Phase separation; Atom probe tomography; Clustering; Radial distribution function RDF ;

    Sammanfattning : Duplex stainless steels (DSSs) are important engineering materials due to their combination of good mechanical properties and corrosion resistance. However, as a consequence of their ferrite content, DSSs are sensitive to the so-called ‘475°C embrittlement’, which is induced by phase separation, namely, the ferrite decomposed into Fe-rich ferrite (α) and Cr-rich ferrite (α'), respectively.

    Sammanfattning : Stainless steels are very important engineering materials in a variety of applications such as in the food industry and nuclear power plants due to their combination of good mechanical properties and high corrosion resistance. However, ferrite-containing stainless steels are sensitive to the so-called ‘475°C embrittlement’, which is induced by phase separation of the ferrite phase, where it decomposes into Fe-rich ferrite (α) and Cr-rich ferrite (α').
