  1. 1. On deoxidation practice and grain size of austenitic manganese steel

    Författare :Dimitrios Siafakas; Anders Jarfors; Taishi Matsushita; Johan Nils Ahlström; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; carbides; oxides; Hadfield stål; desoxidering; kornstorlek; ympning; partiklar; karbider; oxider;

    Sammanfattning : The exceptional wear resistance and work hardenability, place Hadfield steel as one of themost important materials for manufacturing cast components used in the mining, crashing,drilling, and excavation industries. In all metallic alloys used for component casting, themechanical properties are highly influenced by the microstructure of the material. LÄS MER

  3. 2. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties

    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

  4. 3. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101

    Författare :Elin M. Westin; John Ågren; Hannu Hänninen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; welding; HAZ; nitrogen; manganese; microstructure; austenite formation; phase balance; precipitates; element distribution; segregation; depletion; solidification; pitting corrosion resistance; solidification; element loss; evaporation; deposition; weld oxide; thermo-mechanical simulation; thermodynamic modelling; EPMA; XPS; post-weld cleaning; pickling; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : Duplex stainless steels can be very attractive alternatives to austenitic grades due to their almost double strength at equal pitting corrosion resistance. When welding, the duplex alloys normally require addition of filler metal, while the commodity austenitic grades can often be welded autogenously. LÄS MER

  5. 4. Stacking fault energy and deformation behaviour of austenitic stainless steels: a joint theoretical-experimental study

    Författare :Dávid Sándor Molnár; Levente Vitos; Göran Engberg; Guocai Chai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic stainless steel; deformation properties; stacking fault energy; electron backscatter diffraction; ab initio; Teknisk materialvetenskap; Materials Science and Engineering; Steel Forming and Surface Engineering;

    Sammanfattning : Austenitiska rostfria stål är främst kända för sin exceptionella korrosionsbeständighet. De har en ytcentrerad kubisk (FCC) struktur som stabiliseras genom att nickel, mangan eller kväve tillsätts till Fe-Cr legeringen. Fe-Cr-Ni-systemet kan utökas ytterligare genom tillsats av andra element såsom Mo, Cu, Ti, C, etc. LÄS MER

  7. 5. Stacking faults, deformation-induced martensite and micromechanics of metastable austenite in steels studied by high-energy synchrotron X-ray diffraction

    Författare :Benjamin Neding; Peter Hedström; Dmytro Orlov; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic stainless steel; deformation-induced martensitic transformation; stacking fault energy; high-energy X-ray diffraction; HEXRD; high-energy X-ray diffraction microscopy; HEDM; medium Mn steel; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Austenitic stainless steels are known for their remarkable corrosion resistance and exhibit a very high ductility and toughness. They posses the face centered cubic crystal structure. LÄS MER
