  1. 26. Evaluating spreadability of metallic powders for powder bed fusion processes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Vignesh Hari; [2020]
    Nyckelord :Additive manufacturing; spreadability; flowability; Additiv tillverkning; spridbarhet; flytbarhet; mätetal;

    Sammanfattning : Additive  manufacturing  technologies  are  widely  used  in  aerospace,  space,  and  turbine industries. Parts can be manufactured directly by selectively adding materials layer-by-layer. A key aspect that is critical to the quality of the final component being manufactured is the powder characteristics. LÄS MER

  3. 27. Naturalistiska perennplanteringar på gröna tak med biokol i substratet : en undersökning om biokolets påverkan av potentiella växtval på gröna tak, samt hur ekologi och design kan samverka för att skapa mer hållbara planteringar

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Carin Wincent; [2020]
    Nyckelord :naturalistisk plantering; biokol; gröna tak; substrat; ekologi; design; perennplantering; växtbäddsscenario; potentiella växtarter;

    Sammanfattning : Gröna tak kan generera många välbehövda ekosystemtjänster och vara en av lösningarna för att hantera de klimatförändringar vi står inför. De kan också ha en positiv och lugnande inverkan på oss människor i den stressade värld vi lever i. LÄS MER

  4. 28. Prediction of Process Parameters for Powder Bed Fusion Using Electron Beam

    Master-uppsats, KTH/Materialvetenskap

    Författare :Teodor Haglund; [2020]
    Nyckelord :EBM; PBF-EB; Power Bed Fusion; Process Parameters; Parameters; Prediction;

    Sammanfattning : The Powder Bed Fusion using Electron Beam (PBF-EB) process is a highly complex additive manufacturing process. There are a very limited number of materials that have been used successfully, which limits the applications of the process, despite its well-documented advantages over conventional manufacturing.

  5. 29. Nutrient dynamics in pak choi cultivation fertilized with biogas digestate : effects of non-nutrient digestate elements and amendment with mineral nutrients

    Master-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Kristina Weimers; [2020]
    Nyckelord :Biogas digestate; pak choi; Brassica rapa; ssp. chinensis; ‘Joy Choi’; greenhouse; soilless production; peat-based growing media; biostimulants; nitrification; nutrient recovery efficiency; phosphorus; sulphur;

    Sammanfattning : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. LÄS MER

  7. 30. Process development for H13 tool steel powder in binder jet process

    M1-uppsats, Högskolan i Gävle/Maskinteknik

    Författare :George Persson; [2020]
    Nyckelord :Additive manufacturing; H13; toolsteel; binder jetting; processutveckling.;

    Sammanfattning : Additive manufacturing brings versatility and new degree of freedom for part design and manufacturing possibilities. Binder jetting is powder bed printing technique that does not require direct energy transfer rather binding powder metal particles through mechanical entanglement by use of the organic binder. LÄS MER
