    Författare :Elin M. Westin; John Ågren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; welding; weld metal; HAZ; nitrogen; manganese; austenite formation; phase balance; precipitates; pitting resistance; heat input; solidification; element loss; evaporation; deposition; weld oxides; discoloration; mechanical properties; thermo-mechanical simulation; Geeble; GTA; laser; LOM; SEM; EDS; TEM; Leco; EPMA; ferroxyl test; XPS; post weld cleaning; pickling; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. LÄS MER

  7. 5. From Interoperability to Harmonization in Metadata Standardization : Designing an Evolvable Framework for Metadata Harmonization

    Författare :Mikael Nilsson; Ambjörn Naeve; Nils Enlund; Marko Turpeinen; Stuart Sutton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metadata; dublin core; IEEE LOM; RDF; semantic web; interoperability; standardization; Computer science; Datavetenskap;

    Sammanfattning : Metadata is an increasingly central tool in the current web environment, enabling large-scale, distributed management of resources. Recent years has seen a growth in interaction between previously relatively isolated metadata communities, driven by a need for cross-domain collaboration and exchange. LÄS MER
