  1. 1. Corrosion studies on multicomponent TiZrNbTa thin films

    University essay from Uppsala universitet/Strukturkemi

    Author : Asker Jarlöv; [2020]
    Keywords : Corrosion resistance; Multicomponent thin-film; High entropy alloy; TiZrNbTa; Bipolar plates; Magnetron sputtering;

    Abstract : The goal of this work was to evaluate the electrochemical properties of TiZrNbTa thin films deposited by magnetron sputtering using an industrial physical vapor deposition system. Samples were deposited on both Si(001) and 316L stainless steel. READ MORE

  2. 2. Heat Treatment and Secondary Phase Formation in FeCrNi Medium Entropy Alloys

    University essay from KTH/Materialvetenskap

    Author : Amanda Carsbring; [2020]
    Keywords : ;

    Abstract : The topics of high entropy alloys (HEA) and medium entropy alloys (MEA) have been heavily researched in recent years. A HEA usually consists of five or more base elements, and a MEA would have three or four base elements. READ MORE

  3. 3. Design and Development of Light Weight High Entropy Alloys

    University essay from Högskolan i Jönköping/JTH, Material och tillverkning

    Author : Akash Avinash Gondhalekar; [2019]
    Keywords : High Entropy Alloys; CCAs; Solid Solutions; Intermetallic Compounds; Thermodynamic; Multicomponent; Microstructure; Mechanical Properties;

    Abstract : The main aim of this thesis was to design and develop new Aluminium based compositionally complex alloys (CCAs) using the high entropy alloy (HEA) concept, and to understand their evolution of microstructures during casting and also after the secondary process which is heat-treatment, and finally to evaluate their subsequent mechanical properties. Prior to the development of alloys, a computational technique ThermoCalc was used which helped in understanding the phase formation in various results. READ MORE

  4. 4. Magnetic Properites in Alloy Systems

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Nanny Strandqvist; [2017]
    Keywords : Magnetocaloric effect; adiabatic temperature change; magnetic entropy change; magnetocaloric materials; magnetic refrigerator;

    Abstract : The attention for materials displaying high magnetocaloric effect (MCE) has grown during the past 30 years. One of the most important properties of MCE is the adiabatic temperature change ( ). The main aim of this work was to develop a method to measure the temperature change ( ) for magnetocaloric materials in a changing magnetic field. READ MORE
