  1. 1. Theoretical investigation of Co-dependence in magnetic high-entropy alloys

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Johan-Michael Kurak; [2023]
    Keywords : ;

    Abstract : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. READ MORE

  3. 2. Multicomponent TiNbCrAl nitride films produced by DCMS and HiPIMS

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Grzegorz Sadowski; [2021]
    Keywords : High entropy nitrides; thin film; HiPIMS; hardness;

    Abstract : High entropy alloys (HEAs) are made of at least five principal elements in near-equimolar proportions. The vast number of possible alloys and unconventional combinations of properties are the main benefits of HEAs. Ti, Nb, Cr, Al and N were chosen in order to create a hard, corrosion resistant coating with good thermal stability. READ MORE

  4. 3. Corrosion Resistant Multi-Component Coatings for Hydrogen Fuel Cells

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Jakob Steneteg; [2021]
    Keywords : Coatings; Hydrogen Fuel Cells; Multi-Component; High Entropy Alloys; Corrosion Resistance;

    Abstract : Multi-component coatings and high entropy alloys have in recent years attracted great interest for research, since they have shown to exhibit properties greater than the com- ponents of their parts. Today’s climate challenges requires transitioning from fossil fuels to renewable energy sources which demands use of new technology and new innovations. READ MORE

  5. 4. Setup Implementation for a Direct Measurement Technique of the Magnetocaloric Effect

    University essay from KTH/Materialvetenskap

    Author : Ferdinand Posva; [2020]
    Keywords : Magnetocaloric effect; Direct method; Gadolinium; High entropy alloys;

    Abstract : This project presents an attempt to construct a setup and implement a reliable technique for measuring the magnetocaloric effect (MCE) on various materials via a direct method for the acquisition of the data. The main objective of the latter is to produce a ∆Tadiabatic vs T graph over a reasonable temperature span (-100◦C up to 220◦C) by thermal monitoring of a magnetic material exposed to an oscillating magnetic field with a maximum strength of 1.

  6. 5. 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
