  1. 1. Evaluation of the Industrial Feasibility of Hydrogen Production with Small Modular Reactors : With insights from a case study in Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Elias Ljunggren; [2023]
    Nyckelord :Small Modular Reactors; SMR; Hydrogen; Levelized Cost of Hydrogen; Hydrogen Purchase Agreement; Små Modulära Reaktorer; SMR; Vätgas; Utjämnad Kostnad för Vätgas; Vätgasköpavtal;

    Sammanfattning : This report conducts an in-depth examination of the potential for Small Modular Reactor (SMR)-based hydrogen production in Sweden's emerging nuclear market. Aligned with Sweden's ambitious targets of achieving carbon dioxide neutrality by 2045 and transitioning its steel and industry sectors to fossil-free production by 2035, the report explores the unique value proposition that a focal company can offer.

  3. 2. Analysis of trends in policies and pathways for climate neutrality within the steel industry : A case study of powder metal company Höganäs AB

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Anna Westerberg; Emma Mörlin; [2021]
    Nyckelord :powder metal; climate neutral; decarbonising; steel industry; IPCC;

    Sammanfattning : To be in line with the Paris Agreement and mitigate average temperature rise to 1.5°C, and to a maximum of 2°C, greenhouse gas emissions will have to be reduced close to zero before mid-century. If these targets are to be reached, rapid and complete decarbonisation of every sector within the global economy is required. LÄS MER

  4. 3. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Caroline Lejonklo; [2019]
    Nyckelord :Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

    Sammanfattning : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

  5. 4. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules

    Master-uppsats, KTH/Materialvetenskap

    Författare :Emil Strand; [2018]
    Nyckelord :Hot isostatic pressing; hollow glass microspheres; powder metallurgy; oxide reduction; surface oxides; hydrogen;

    Sammanfattning : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).

  7. 5. Optimering av sintrade kugghjul

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Mario Sosa; [2012]
    Nyckelord :;

    Sammanfattning : Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. LÄS MER
