1. 1. Microstructures and Compressive Strength of Lake Ice in Sweden A structural Documentation and Compressive Strength Analysis of Lake Ice Cores from Uppsala, using the SonReb Method

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Julia Ladefoged; [2023-08-18]
   Keywords : ;

   Abstract : Lake ice have been utilized by humans through centuries, as transportation routes and recreational activities to name a few (Sharma et al., 2019). Despite our frequent usage of lake ice there is a lack of extensive knowledge of it. READ MORE

3. 2. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

   University essay from KTH/Materialvetenskap

   Author : Felicia Larsson; [2023]
   Keywords : ;

   Abstract : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. READ MORE

4. 3. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

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

   Author : Abderrahim Ait ouakrim; [2023]
   Keywords : Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

   Abstract : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

5. 4. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Julia Ibstedt; [2023]
   Keywords : Topology optimization; Multi-scale topology optimization; Machine learning; Gaussian process; Homogenization; Inverse homogenization; Anisotropic materials; Symmetry groups; Material property space; Topologioptimering; Flerskalig topologioptimering; Maskininlärning; Gaussian process; Homogenisering; Anisotropa material; Symmetrigrupper; Materialegenskapsrymd;

   Abstract : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

6. 5. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Belén Alonso Rancurel; [2023]
   Keywords : austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

   Abstract : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.
