1. Impact of Residual Stress on the Warm Pre-Stressing Effect
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. LÄS MER
2. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/MikrosystemteknikSammanfattning : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. LÄS MER
3. Fabricability of a high alloy tool steel produced with LPBF, with a focus on part geometry
Master-uppsats, Karlstads universitetSammanfattning : Additive manufacturing (AM) is a promising manufacturing process that provides that ability to fabricate components with complex geometries with relatively low lead times compared to other manufacturing processes. This allows for more freedom of design, as prototypes can easily be produced throughout the development process. LÄS MER
4. Simulation of Residual Stresses in Cemented Carbide
Master-uppsats, KTH/Teknisk mekanikSammanfattning : Cemented carbides are used in a multitude of applications within machining as they can withstand tough conditions. Therefore, the stress state in a virgin material is of interest. LÄS MER
5. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. LÄS MER
