  2. 16. Inside The Miscibility Gap : Nanostructuring and Phase Transformations in Hard Nitride Coatings

    Author : Lars Johnson; Lars Hultman; Magnus Odén; Michael Kopnarski; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis is concerned with self-organization phenomena in hard and wear resistant transition-metal nitride coatings, both during growth and during post deposition thermal annealing. The uniting physical principle in the studied systems is the immiscibility of their constituent parts, which leads, under certain conditions, to structural variations on the nanoscale. READ MORE

  4. 17. Thermal stability and mechanical properties of TiAlN-based multilayer and monolithic coatings

    Author : Axel Knutsson; Magnus Odén; Lennart Karlsson; Grégory Abadias; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis explores the thermal stability, microstructure, mechanical properties and cutting performance of multilayer and monolithic cubic TiAlN hard coatings. The aim is to increase the understanding of how the coatings’ microstructure and properties are affected by a layered structure when exposed to high temperatures. READ MORE

  5. 18. Multiscale materials design of hard coatings for improved fracture resistance and thermal stability

    Author : Phani Kumar Yalamanchili; Magnus Odén; Naureen Ghafoor; Emilio Jiménez-Piqué; Jon Molina; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Physical vapor deposited hard coatings comprised of cubic (c) transition metal (TM)-Al-N, and (TM)-Si-N are the current workhorse materials for a large number of metal cutting and wear resistant applications to fight against the extreme conditions of temperature and stress simultaneously. In spite of a high degree of sophistication in terms of material choice and microstructural design, a lower fracture resistance and limited thermal stability of the coatings remains a technological challenge in the field.

  6. 19. Wear behavior of Ti1-xAlxN-based coatings during turning

    Author : Maiara Moreno; Lina Rogström; Magnus Odén; Jon M. Andersson; José Luis Endrino; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Ti1-xAlxN coatings are extensively used on cutting tools used for metal cutting. In this thesis, the wear behavior of TiN, TiAlN with different Al-content, and TiAlWN and TiAlMoN coatings is investigated after turning, using electron microscopy and X-ray absorption spectroscopy techniques.

  7. 20. High pressure and high temperature behavior of TiAlN

    Author : Niklas Norrby; Magnus Odén; Mats Johansson Johansson; Helen Blomqvist; Linköpings universitet; []
    Keywords : ;

    Abstract : This licentiate thesis mainly reports about the behavior of arc evaporated TiAlN at high pressures and high temperatures. The extreme conditions have been obtained in metal cutting, multi anvil presses or diamond anvil cells. Several characterization techniques have been used, including x-ray diffraction and transmission electron microscopy. READ MORE
