  1. 1. Cantor-Alloy-Based Multicomponent Nitride Thin Films

    Författare :Smita Gangaprasad Rao; Per Eklund; Arnaud Le Febvrier; Yutao Pei; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin films; Multicomponent alloys; Magnetron sputtering;

    Sammanfattning : In this Thesis, I have investigated multicomponent alloy based thin films synthesized by magnetron sputtering. The studies in the thesis are centered around the phase diagram of the CrFeCoNi nitrogen containing system. LÄS MER

  3. 2. Ab initio atomistic simulation of metals and multicomponent alloys

    Författare :Fuyang Tian; Levente Vitos; Kalevi Kokko; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high entropy alloys; ab inito;

    Sammanfattning : Ab initio theory provides a powerful tool to understand and predict the behavior of materials. This thesis contains both of these aspects. First we use ab initio alloy theory to investigate a new kind of complex alloy (high-entropy alloy). LÄS MER

  4. 3. Investigations of the corrosion resistances of magnetron sputtered multicomponent materials : A study on high entropy alloys, high entropy sublattice ceramics, and metallic glasses

    Författare :Aishwarya Srinath; Leif Nyholm; Ulf Jansson; Rebecka Lindblad; Bernard Normand; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Corrosion resistance; high entropy alloys; magnetron sputtering; thin films; protective coatings;

    Sammanfattning : The corrosion resistances of sputter deposited AlCrNbYZrN, CrNbTiTaWC and TaNiSiC alloys were assessed in acidic and alkaline environments. Compositionally complex alloying strategies, and whether they produced coatings with superior corrosion resistances, were explored. LÄS MER

  5. 4. Configurational and Magnetic Interactions in Multicomponent Systems

    Författare :Björn Alling; Igor A. Abrikosov; Lars Hultman; Stefan Blügel; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic interactions; Configurational thermodynamics; Curie temperature; theoretical physics; magnetism; TiAlN; TiN; AlN; CrN; TiCrN; nitrides; NiMnSb; NiCuMnSb; Heusler alloys; spintronics; half-metallic; spinodal decomposition; first-principles; ab-initio; Magnetism; Magnetism;

    Sammanfattning : This thesis is a theoretical study of configurational and magnetic interactions in multicomponent solids. These interactions are the projections onto the configurational and magnetic degrees of freedom of the underlying electronic quantum mechanical system, and can be used to model, explain and predict the properties of materials.
