    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kiruna; Gällivare; structural geology; Paleoproterozoic; deformation; Malmgeologi; Ore Geology;

    Sammanfattning : This thesis covers the structural evolution of the Kiruna‑Gällivare area in the northern Norrbotten ore province, Sweden. The study area hosts several economically significant iron oxide-apatite (IOA) deposits and includes the type locality for this ore type. 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. Impact wave process modeling and optimization in high energy rate explosive welding

    Författare :Mohammad Tabatabaee Ghomi; Jafar Mahmoudi; Nils Erik Hannerz; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Explosive welding; Impact; Wave; Deformation; Velocity; Engineering mechanics; Teknisk mekanik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Impact waves are used in many different industries and are classified according to whether they cause plastic or elastic deformations. In the plastic deformation mode, these waves can be used to produce special electrical joints. In the elastic deformation mode, they can be used to detect leakage or to measure the thickness of pipes. LÄS MER
