16. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. LÄS MER
17. Assessment of aggregate structure in porous asphalt using X-ray computed tomography
Master-uppsats, KTH/Väg- och banteknikSammanfattning : X-ray computed tomography is a technique that has been successfully utilized to characterize internal microstructure of asphalt mixtures. The city of Linköping (Sweden) developed an action plan to reduce noise; accordingly KTH and VTI developed a method to determine air void content in porous asphalt using x-ray computed tomography and an image processing software called ImageJ.

18. Increased build rate by laser powder bed fusion of SSAB steel powder
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : SSAB has built a pilot gas atomization facility looking to expand their expertise of steel into the metal powder and additive manufacturing industry. Laser powder bed fusion is an additive manufacturing method that melts and fuse metal feedstock powder together layer by layer using a high intensity laser. LÄS MER
19. Experimental Testing of EPS-foam
Master-uppsats, KTH/HållfasthetsläraSammanfattning : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.

20. Swedish “tofu” from faba beans : a textural and structural analysis
Kandidat-uppsats, SLU/Department of Molecular SciencesSammanfattning : Tofu, a traditional soybean product, is a popular plant-based alternative which could potentially be produced from Swedish-grown faba beans (Vicia faba L.). The aim of this project was to asses the viability of producing a tofu-like faba bean product using food grade gypsum (calcium sulphate) as coagulant. LÄS MER
