  2. 1. Using genomics to improve Bacillus anthracis diagnostics and outbreak investigations

    Author : Joakim Ågren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The bacterium Bacillus anthracis causes the disease anthrax, primarily in herbivores but many mammals are susceptible to the disease. Its infective form is as a dormant spore that can lie in the soil for decades. READ MORE

    Abstract : Fe-Cr based steels, i.e. stainless steels, possessing a combination of excellent corrosion resistance and good mechanical properties, have indispensable applications ranging from low-end cooking utensils, to sophisticated components for nuclear power plants. READ MORE

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

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

    Abstract : 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.
