  1. 26. Process and microstructure development of a LPBF produced maraging steel

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Kenny Johansson; [2020]
    Keywords : Maraging steels; additive manufacturing; Laser Powder Bed Fusion; LPBF; additiv tillverkning; maråldringsstål; pulverbädd;

    Abstract : Additive manufacturing (AM) has the possibility of producing complex-shaped components which can not be produced by conventional manufacturing methods. This gives the opportunity for designers to freely think outside the design spectra which is otherwise limited by conventional manufacturing methods. READ MORE

  3. 27. Orientation dependant grain boundary diffusion in polycrystals

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Author : Kevin Hult Blixt; [2020]
    Keywords : Technology and Engineering;

    Abstract : Grain boundary diffusion in polycrystals is of importance in industrial applications as it often, to a large degree, dictates the effective rate of diffusion in polycrystals. For impurity diffusion the enrichment of impurities within the material will in turn change the material properties, such as ductility and fatigue rates. READ MORE

  4. 28. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Eva Smedborn Pausson; [2019]
    Keywords : ;

    Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

  5. 29. Probiotikans effekt på avvänjningsdiarré hos smågrisar : kan utfodring med probiotika öka tillväxten

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Johanna Lilja; [2019]
    Keywords : digesionskanal; mikroorganismer; mikrobiota; zink; tillväxt; hälsoeffekter;

    Abstract : Vid avvänjning utsätts smågrisar för flera stressfyllda moment som ofta resulterar i avvänjningsdiarré. Avvänjningen kan medföra negativa effekter på mukosan och mikrobiotan i digestionskanalen och därmed främja patogener som i sin tur ökar risken för avvänjningsdiarré. READ MORE

  6. 30. Developing an advanced spline fatigue prediction method

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Abdallah Zarad; [2019]
    Keywords : fatigue; fatigue prediction; splines; stress analysis; Finite element analysis;

    Abstract : Fatigue failure is one of the most critical issues in industry nowadays as 60 to 90 percent of failures in metals are due to fatigue. Therefore, different methods and approaches are developed to estimate the fatigue life of metallic parts. READ MORE
