  1. 1. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Ivan Rashid; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. READ MORE

  3. 2. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

    University essay from KTH/Materialvetenskap

    Author : Filip Ivarsson; [2022]
    Keywords : Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

    Abstract : 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.

  4. 3. Automatic segmentation of microstructures in metals : A computer vision approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oscar Larsen; [2022]
    Keywords : Image Processing; Computer Vision; Machine Learning; Deep Learning; Metallurgy; Segmentation; Bildbehandling; Datorseende; Maskininlärning; Djupinlärning; Metallurgi; Segmentering;

    Abstract : 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. READ MORE

  5. 4. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205

    University essay from Jönköping University/Tekniska Högskolan

    Author : Max Holmberg; Pontus Sundberg; [2022]
    Keywords : Aluminium Alloy A205;

    Abstract : 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. READ MORE

  6. 5. Machine Learning Methods for Segmentation of Complex Metal Microstructure Features

    University essay from KTH/Materialvetenskap

    Author : Daniel Fredriksson; [2022]
    Keywords : Machine learning; Metallography; Automatic segmentation; Complex microstructures; Random Forest classifier.; Maskininlärning; Metallografi; Automatisk segmentering; Komplex mikrostruktur; Random Forest klassificerare;

    Abstract : 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. READ MORE
