  1. 1. Steel Beyond Coal : Socio-Technical Change and the Emergent Politics of Steel Decarbonisation

    Författare :Valentin Vogl; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel; coal; climate change; decarbonisation; socio-technical transitions; sustainability;

    Sammanfattning : The steel industry is responsible for 8% of all anthropogenic greenhouse gas emissions and is the second largest user of coal after the power sector. The main emission source in steel production is the blast furnace, which converts iron ore and metallurgical coal into pig iron that is then further refined into steel. LÄS MER

  3. 2. The comfort of alignment: Mining, green steel, and killjoy desires in Sweden/Sápmi

    Författare :Georgia de Leeuw; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; extractivism; mining; green steel; iron ore; comfort; alignment; Sweden; Sápmi;

    Sammanfattning : This dissertation deals with Swedish extractivism in Sápmi through the examples of a planned iron ore mine in Gállok/Kallak and the hydrogen-based steel transition. The main aim is to understand the trust that is placed in extraction as a means to arrive at a happy, prosperous, green future. LÄS MER

  4. 3. The Mussel Adhesive Protein (Mefp-1) : A GREEN Corrosion Inhibitor

    Författare :Fan Zhang; Jinshan Pan; Douglas C. Hansen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon steel; mussel adhesive protein; Mefp-1; inhibitor; adsorption; film forming; complexation; cross-linking; ceria nanoparticle; composite film; EIS; AFM; QCM-D; ATR-FTIR; Confocal Raman Micro-spectroscopy; DFT calculation;

    Sammanfattning : Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. LÄS MER

  5. 4. On the processing of starch consolidated high speed steel - Microstructure and tribological properties

    Författare :Peter Harlin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribological properties; green body; microstructure; porosity; high speed steel; Starch consolidation; super solidus liquid phase sintering; mechanical properties;

    Sammanfattning : This thesis focuses on processing of high speed steel (HSS) powder into components using starch consolidation (SC) and supersolidus liquid phase sintering (SLPS). The work consists of four parts. First, the possibilities and constrains of the SC process are investigated and the role of starch in the green body fabrication clarified. LÄS MER

  7. 5. Framtidens arbete i den digitala och gröna omställningen : Förändring och stabilisering

    Författare :Felix Lundmark; Lena Abrahamsson; Fredrik Sjögren; Therese Öhrling; Cecilia Berlin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arbetsvetenskap; Human Work Sciences;

    Sammanfattning : This dissertation focuses on the construction of future steel work and work environment in relation to the ongoing digital and green transitions. The transitions include a clear focus on technology and has so far been lacking a focus on work. LÄS MER
