  1. 1. Apparent density for water atomized low-carbon steel powder

    University essay from KTH/Materialvetenskap

    Author : Simon Lindström; [2023]
    Keywords : ;

    Abstract : Carbon content does not affect the apparent density for water atomized iron powder monotonically. At low carbon content, around 0.1 wt %, apparent density is higher than a similar powder with 0.3 wt % carbon. READ MORE

  3. 2. Michael additions utilizing transition-metal-catalysts, Scope and limitations

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ruben Hansson; [2023]
    Keywords : Green chemistry; transition metal; rare earth metal; Michael addition; Yb; Zr; Hf; analytical chemistry; Chemistry;

    Abstract : The effect that organic solvents have on the environment and the intrinsic risk that come with using them should be limited. By replacing organic solvents with less harmful solvents, such as water, and with more effective catalysts can risks intrinsic to organic solvents be minimized or eliminated. READ MORE

  4. 3. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  5. 4. The Effect of Process Parameters on Columnar-To-Equiaxed-Transition (CET) During Electron Beam-Powder Bed Fusion of Ferritic Stainless Steel

    University essay from KTH/Materialvetenskap

    Author : Doom Eleanor Ihensekhien; [2022]
    Keywords : Additive manufacturing; E-PBM; Inoculation; process parameters; TiN; CET;

    Abstract : Electron Beam Powder Bed Fusion manufacturing of components is an additive manufacturing process that is complex and has widespread advantages for aerospace and many industrial processes. It reduces costs and has a larger powder particle size requirement. READ MORE

  6. 5. An Initial Analysis of Slurry Transportation in Subarctic Environment

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Wilhelm Friberg; [2021]
    Keywords : Slurry Transport;

    Abstract : In today’s economy, it is important to have a sustainable business model where as little as possible goes to waste or finding solutions to create something useful out of by-products. Therefore, LKAB are looking to make a large investment into creating an infrastructure of several plants to turn tailings from the production of iron ore into usable products for several industries which LKAB has designated project ReeMAP (Rear Earth Elements and MonoAmmonium Phosphate).
