  1. 1. Machine Learning Methods for Segmentation of Complex Metal Microstructure Features

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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

  3. 2. Understanding the effect of temperature and time on Gamma prime coarsening for Nickel-base superalloy Haynes 282

    Master-uppsats, KTH/Materialvetenskap

    Författare :Kevin Vattappara; [2019]
    Nyckelord :Haynes 282; gamma prime 𝛾′ ; Arc-heat treatment; COMSOL modelling; isothermal transformation; coarsening; Thermo-Calc simulations;

    Sammanfattning : Haynes 282 is a gamma prime (𝛾′)-strengthened nickel base superalloy developed in 2005, exhibiting a good combination of high temperature properties and fabricability. Microstructural features such as 𝛾′ and carbides play an important role in deriving the mechanical properties of the alloy during heat treatment. LÄS MER

  4. 3. Segmentation, Analysis, and Modelling of Microstructure in Cortical Bone, based on X-ray Microtomography

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Elin Törnquist; [2017]
    Nyckelord :Cortical bone; Biomechanics; Segmentation; K-mean clustering; Microstructure; X-ray Microtomography; Mathematics and Statistics; Medicine and Health Sciences; Technology and Engineering;

    Sammanfattning : The microstructure in cortical bone greatly affect the toughness of the bone and the crack propagation during fracture. The two main structural features, Haversian canals and osteons, have been previously studied in order to increase the knowledge of the biomechanics of bone. LÄS MER
