  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. An analytical method for quickly evaluating the performances of refractory alloys in sCO2 Brayton cycle applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jiaqi Yang; [2023]
    Keywords : ;

    Abstract : A rapid and effective analytical method has been developed to assess the performance of structural materials in sCO2 power cycle applications. This method combines a conjugate heat transfer model, considering constant heat flux boundary conditions, with a corresponding mechanical model. READ MORE

  4. 3. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Felix Hansen; Mathias Berglund; [2023]
    Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

    Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE

  5. 4. Waste-derived hard carbon anode materials for sodium-ion batteries : The potential of using cardboard as precursor material in sodium-ion batteries for hard carbon production in Sweden

    University essay from KTH/Materialvetenskap

    Author : Axel Björlin; Alexander Hansson; Yanxi Lucie Zhou; [2023]
    Keywords : ;

    Abstract : In recent years, sodium ion batteries (SIBs) have emerged as a strong contender to lithium-ion batteries (LIBs). The most promising anode for the SIBs is hard carbon (HC), which can be derived from a wide variety of raw materials and waste globally. READ MORE

  6. 5. Transformation of In-Flight Measured Loads to a Fatigue Test Spectrum

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Patrick Dümig; [2022]
    Keywords : Aerospace engineering; Aircraft load spectra; ASIP; Crack growth; Fatigue testing; Flight loads; Flight test; Fracture mechanics; FSFT; In-flight measurements; Load spectrum reduction; Racetrack filtering; Strain gauge measurements;

    Abstract : Fatigue is a well-recognized issue in lightweight and high-performance aircraft structures. As fatigue failures have led to serious accidents and caused significant economic impact in the past, design against fatigue is crucial. READ MORE
