6. Modelling Gas Flow Behaviour in Gas Atomizer
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

7. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate
Master-uppsats, KTH/MaterialvetenskapSammanfattning : 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. LÄS MER
8. PFAS- En sammanfattning av ny forskning, med ett fokus på föroreningskällor, provtagning, analysmetoder och saneringsmetoder
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : PFAS (per- and polyfluoroalkyl substances) is a large group of pollutants that, over the last decade have been of great academic concern since it has been found all around the globe. PFAS is ubiquitous in our environment and frequently found in low background concentrations in soil and water; recent research has also found that PFAS occur in biotic samples, such as fish and plants.

9. Supercooling Simulation of Latent Heat Based Storage : A simulation model built in COMSOL Multiphysics
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The energy demand in the building sector makes up a large portion of our energy consumption. The industrial sector is also energy intense and oftentimes loses a great deal as surplus heat. LÄS MER
10. The Effect of Process Parameters on Columnar-To-Equiaxed-Transition (CET) During Electron Beam-Powder Bed Fusion of Ferritic Stainless Steel
Master-uppsats, KTH/MaterialvetenskapSammanfattning : 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. LÄS MER
