  1. 1. Crucial Parameters for Additive Manufacturing of Metals : A Study in Quality Improvement

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

    Författare :Lina Berglund; Filip Ivarsson; Marcus Rostmark; [2019]
    Nyckelord :Additive manufacturing; Production parameters; Sandvik; Quality improvement; Selective laser melting; Powder bed fusion; Process control;

    Sammanfattning : Production by Additive Manufacturing creates opportunities to make customized products in small batches with less material than in traditional manufacturing. It is more sustainable and suitable for niche products, but entails new production demands to ensure quality. LÄS MER

  2. 2. Fire Safety of Facades

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Bogdan-Grigore Branisteanu-Albulescu; [2019]
    Nyckelord :polystyrene; graphene; façade; pyrolysis; Technology and Engineering;

    Sammanfattning : Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. LÄS MER

  3. 3. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced Composites

    Master-uppsats, KTH/Energiteknik; KTH/Energiteknik

    Författare :JiaCheng Lin; HaoRan Teng; [2019]
    Nyckelord :Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

    Sammanfattning : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. LÄS MER

  4. 4. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Hellgren Simon; [2019]
    Nyckelord :MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Sammanfattning : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. LÄS MER

  5. 5. Mass Balance of the High-Arctic Glacier Nordenskiöldbreen, Svalbard, in a Changing Climate

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten och landskapslära

    Författare :Maja Gustavsson; [2019]
    Nyckelord :Mass balance; glacier; Nordenskiöldbreen; climate change; Massbalans; glaciär; Nordenskiöldbreen; klimatförändringar;

    Sammanfattning : Melting glaciers are the major contributor to sea level rise. Glaciers are sensitive indicators of climate change and current experience strong developments in a rapidly warming Arctic environment. LÄS MER
