11. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides
Master-uppsats, KTH/MaterialvetenskapSammanfattning : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this thesis aims to broaden the knowledge and answer whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

12. Automatic segmentation of microstructures in metals : A computer vision approach
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The microstructures of a metal determine the physical, electrical and chemical properties of the metal, and analysis of microstructures is therefore an important part of materials science. Modern microscopes are capable of generating a lot of high-quality micrographs in a short period of time. LÄS MER
13. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205
Kandidat-uppsats, Jönköping University/Tekniska HögskolanSammanfattning : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. LÄS MER
14. Machine Learning Methods for Segmentation of Complex Metal Microstructure Features
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Machine learning is a growing topic with possibilities that seems endless with growing areas of applications. The field of metallography today is highly dependent on the operators’ knowledge and technical equipment to perform segmentation and analysis of the microstructure. Having expert dependents is both costly and very time-consuming. LÄS MER
15. Mikrostrukturen och Ex-dagseffekten : Påverkar mikrostrukturen den svenska börsmarknaden?
Kandidat-uppsats, Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakultetenSammanfattning : Bakgrund: En fungerande kapitalmarknad är en förutsättning för en nations innovation,vilket i sin tur är fundamentalt för att uppnå ekonomisk tillväxt. Därav blir förståelsen för hurkapitalmarknaden fungerar av största vikt. LÄS MER
