  1. 1. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3

    University essay from KTH/Fysik

    Author : Serena Ambrosino; [2024]
    Keywords : Uranium nitride; synthesis; ammonolysis; uranium hexafluoride; uranium tetrafluoride; ammonia; X-ray diffraction; microscopy; Urannitrid; syntes; ammonolys; uranhexafluorid; urantetrafluorid; ammoniak; röntgendiffraktion; mikroskopi;

    Abstract : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. READ MORE

  3. 2. The Application of Multivariate Statistical Process Control during Industrial Hot Isostatic Pressing Sintering Processes : A Case study at Seco Tools AB

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Karl Ericsson; [2023]
    Keywords : Multivariate statistical process control; Batch processes; Quality prediction;

    Abstract : This Master's thesis focuses on improving the understanding and monitoring of the Hot Isostatic Pressing (HIP) sintering process used by Seco Tools AB to manufacture cemented carbides for cutting tools. While essential for producing cutting tools with superior hardness and toughness the HIP sintering process introduces a complex relationship between the selected process parameters and the achieved materials properties.

    Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

  5. 4. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects

    University essay from Uppsala universitet/Materialteori

    Author : Judith Bösenecker; [2023]
    Keywords : sintering; heat transfer; transient heat conduction; sintring; värmeöverföring; transient värmeledning;

    Abstract : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. READ MORE

  6. 5. 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
