  2. 16. Deposition and Phase Transformations of Ternary Al-Cr-O Thin Films

    Author : Ali Khatibi; Lars Hultman; Per Eklund; Jon Andersson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin Films; Hard Coatings; Mathematical physics; Matematisk fysik;

    Abstract : This thesis concerns the ternary Al-Cr-O system. (Al1-xCrx)2O3 solid solution thin films with 0.62 gas mixture. As-deposited and annealed (Al1-xCrx)2O3 thin films were analyzed by x-ray diffraction, elastic recoil detection analysis, scanning electron microscopy, transmission electron microscopy, and nanoindentation.

  4. 17. Mechanical characterization and modelling of the fracture behaviour of thin brittle coatings on polymer films

    Author : Marcus Vinícius Tavares da Costa; E. Kristofer Gamstedt; Christoph Kirchlechner; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brittle coating; Polymer substrate; Crack density; Weibull distribution; SEM; Digital image correlation; Finite element modelling; Energy release rate;

    Abstract : Thin brittle coatings with thickness of a few nanometres deposited on flexible polymer substrates form an interesting material combination for food packaging and flexible electronics. This combination may enhance the barrier performance in carton packages. In flexible electronics, coatings could conduct electricity despite their small thickness. READ MORE

  5. 18. Sputter Deposition, Mechanical Properties, and Thermal Stability of Nitride Based Superlattices

    Author : Carolina Engström; Helmut Holleck; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Investigations concerning deposition, mechanical properties and thermal stability of nitride-based superlattice films have been performed. X-ray diffraction and transmission electron microscopy techniques were adopted for microstructural characterization, while nanoindentation hardness and abrasive wear resistance measurements were utilized for evaluation of mechanical properties.

  7. 20. Micro-mechanical characterization and modeling of paper and paperboard

    Author : August Brandberg; Artem Kulachenko; Sören Östlund; Carl Dahlberg; Rami Mansour; Ron Peerlings; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (paperboard). This thesis investigates the mechanical performance of paper and paperboard via micro-mechanical modeling and presents new methods for the mechanical characterization of the micro scale, necessary in such models.
