  2. 1. Combining ab‐initio and machine learning techniques for theoretical simulations of hard nitrides at extreme conditions

    Author : Florian Bock; Igor Abrikosov; Ferenc Tasnadi; Magnus Odén; Martin Friák; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis I focus on combining the high accuracy of first-principles calculations with modern machine learning methods to make large scale investigations of industrially relevant nitride systems reliable and computationally viable. I study the electronic, thermodynamic and mechanical properties of two families of compounds: Ti1−xAlxN alloys at the operational conditions of industrial cutting tools and ReNx systems at crushing pres-sures comparable to inner earth core conditions.

  4. 2. Theoretical understanding of stability of alloys for hard-coating applications and design

    Author : Hans Lind; Igor Abrikosov; Ferenc Tasnádi; Ralf Drautz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The performance of modern hard coating materials puts high demands on properties such as hardness, thermal stability and oxidation resistance. These properties not only depend on the chemical composition, but also on the structure of the material on a nanoscale. READ MORE

  5. 3. A Theoretical Study of Piezoelectricity, Phase Stability, and Surface Diffusion in Disordered Multicomponent Nitrides

    Author : Christopher Tholander; Björn Alling; Ferenc Tasnádi; Lars Hultman; Susanne Mirbt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Piezoelectricity; phase stability; surface diffusion; disordered multicomponent nitrides;

    Abstract : Disordered multicomponent nitride thin film can be used for various applications. The focus of this Licentiate Thesis lies on the theoretical study of piezoelectric properties, phase stability and surface diffusion in multifunctional hard coating nitrides using density functional theory (DFT).

    Abstract : The last hundred years have been full of scientific discoveries leading to technological advances, such as, computers, smart phones, etc. Most of the advances would not have been possible without new discoveries within the vast field of materials science. READ MORE

  7. 5. Lattice dynamics : From fundamental research to practical applications

    Author : Johan Tidholm; Igor A. Abrikosov; Olle Hellman; Ferenc Tasnadi; Gerd Steinle-Neumann; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The reason to perform calculations in material science usually falls into one of two categories: to predict or explain the origin of material properties. This thesis covers first-principle calculations for solids at extreme conditions, from both of the two mentioned categories. READ MORE
