  2. 2. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

    Detta är en avhandling från Gothenburg : Chalmers University of Technology

    Författare :Mathias König; Högskolan i Jönköping.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast Iron; CGI; Microstructure Formation; Mechanical Properties; Modelling; Solidification; Solid State Transformation; Solid state transformation; Mechanical properties; Cast iron; Microstructure formation;

    Sammanfattning : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. LÄS MER

  3. 3. Microstructure Formation and Mechanical Properties in Compacted Graphite Iron

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Mathias König; Högskolan i Jönköping.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; CGI; Microstructure formation; Mechanical properties;

    Sammanfattning : Compacted graphite iron is rapidly becoming an attractive alternative for engine applications in the automotive industry. The improved process control now available that allows CGI components to be cast in a reproducible and reliable way has been the driving force for this development. LÄS MER

  4. 4. Cathodic Arc Synthesis of Ti-Si-C-N Thin Films Plasma Analysis and Microstructure Formation

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Anders Eriksson; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This Thesis explores the arc deposition process and films of Ti-Si-C-N, inspired by the two ternary systems Ti-Si-N and Ti-C-N, both successfully applied as corrosion and wear resistant films. The correlation between cathode, plasma, and film properties are studied for a comprehensive view on film formation. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH

    Författare :Elin M. Westin; KTH.; [2010]
    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; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik 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
