  1. 16. Meeting increased logistical demands : Developing as a small- and medium-sized system supplier

    Författare :Inga-Lill Carlsson; Mats Abrahamsson; Håkan Aronsson; Jens Hultman; Lars Bengtsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Many subcontractors choose to implement a strategy of “system supply” in order to meetincreasing global competition. They are then confronted with increased demands to take agreater overall responsibility in this role. LÄS MER

  3. 17. A theoretical study of mass transport processes on TiN(001) and mechanical properties of TiN- and VN-based ternaries

    Författare :Daniel Edström; Valeriu Chirita; Lars Hultman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns computer simulations, using classical molecular dynamics, of transport processes related to TiN(001) growth. It is motivated from the challenge to understand transport processes at the atomic scale responsible for crystal and film growth and their different growth modes. LÄS MER

  4. 18. Growth and Mechanical Properties of Transition Metal Nitrides and Carbides

    Författare :Daniel Edström; Valeriu Chirita; Lars Hultman; Denis Music; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The atomic-scale dynamical processes at play during film growth cannot be resolved by even the most advanced experimental methods. As such, computational methods, and chiefly classical molecular dynamics, are the only available research tools to study these processes. LÄS MER

  5. 19. Multifunctional nanostructured Ti-Si-C thin films

    Författare :Per Eklund; Lars Hultman; Hans Högberg; G. Ramanath; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : In this Thesis, I have investigated multifunctional nanostructured Ti-Si-C thin films synthesized by magnetron sputtering in the substrate-temperature range from room temperature to 900 °C. The studies cover high-temperature growth of Ti3SiC2 and Ti4SiC3, low-temperature growth of Ti-Si-C nanocomposites, and Ti-Si-C-based multi¬layers, as well as their electrical, mechanical, and thermal-stability properties.

  7. 20. First-principles study of configurational disorder in icosahedral boron-rich solids

    Författare :Annop Ektarawong; Björn Alling; Sergei Simak; Lars Hultman; Biplab Sanyal; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is a theoretical study of configurationally disordered icosahedral boronrich solids, in particular boron carbides, using density functional theory and alloy theory. The goal is to resolve discrepancies, regarding the properties of boron carbides, between experiments and previous theoretical calculations which have been a controversial issue in the field of icosahedral boron-rich solids.
