  1. 11. Titanium Surface Properties: A comparison of titanium from two suppliers

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Adam Almström; [2018]
    Nyckelord :Titanium; Titanium corrosion; Electron backscatter diffraction; EBSD; Glow-discharge optical emission spectroscopy; GDOES; materials chemistry; materialkemi; Technology and Engineering;

    Sammanfattning : This master thesis, completed at the company Alfa Laval studied the surface properties of grade 1 titanium from two different suppliers to examine if there were any significant differences between the two suppliers. Previously titanium from the two suppliers had performed differently at times when used in Alfa Lavals heat exchangers. LÄS MER

  3. 12. Shock metamorphic features in zircon grains from the Mien impact structure : clues to conditions during impact

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Josefin Martell; [2018]
    Nyckelord :Zircon; shock metamorphism; Mien; FRGN zircon; granular texture; Earth and Environmental Sciences;

    Sammanfattning : Jämfört med andra himlakroppar i vårt solsystem så finns det få välbevarade nedslagsstrukturer på jorden. Vi vet att jorden har påverkats av nedslag från rymden i lika stor utsträckning som övriga planeter och att dessa nedslag har influerat jordens geologiska och biologiska utveckling. LÄS MER

  4. 13. WC grain size distribution during sintering of WC-Co cemented carbides

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Oscar Bjäreborn; [2016]
    Nyckelord :hardmetal; cemented carbides; WC; EBSD; grain size distribution; microstructure; coercivity; hardness; toughness; sintering; growth inhibition; Technology and Engineering;

    Sammanfattning : The grain growth of WC in WC-7%Co cemented carbides with Cr-addition was investigated for cemented carbides synthesized from four different raw materials varying in grain size. Cr additions were 4%of the Co binder phase. To investigate the effect of Cr on grain growth two of the raw materials were also synthesized without Cr-additions. LÄS MER

  5. 14. Development of a quantitative method for grain size measurement using EBSD : and Comparison of WC-Co materials produced with different production methods

    Master-uppsats, KTH/Materialvetenskap

    Författare :Fredrik Josefsson; [2012]
    Nyckelord :EBSD; WC-Co; Cemented carbide; Grain size measurement; quantitative;

    Sammanfattning : High performance cutting tools are essential in many industry areas. Cemented carbides (WC-Co) are common materials used for these applications due to the excellent mechanical properties. The mechanical properties of the material are manly dependent on the WC grain size distribution. LÄS MER

  7. 15. Martensitic Transformation in Austenitic Stainless Steels

    Master-uppsats, KTH/Metallografi

    Författare :Reza Naraghi; [2009]
    Nyckelord :Stainless Steel; SEM; EBSD; α’-martensite; Ferritescope;

    Sammanfattning : Martensitic transformation is very important in austenitic stainless steels where the transformation induced plasticity phenomenon provides a combination of good mechanical properties, such as formability and strength. However, the difficulty of predicting the material behaviour is one of the major drawbacks of these steels. LÄS MER
