  4. 3. Accelerating bulk material property prediction using machine learning potentials for molecular dynamics : predicting physical properties of bulk Aluminium and Silicon

    Master-uppsats, Linköpings universitet/Teoretisk Fysik

    Författare :Nicholas Sepp Löfgren; [2021]
    Nyckelord :machine learning; moment tensor potential; kernel ridge regression; molecular dynamics; density functional theory; materials science; data-driven materials design; maskininlärning; molekylärdynamik; täthetsfunktionalteori; materialvetenskap; datadriven materialdesign;

    Sammanfattning : In this project machine learning (ML) interatomic potentials are trained and used in molecular dynamics (MD) simulations to predict the physical properties of total energy, mean squared displacement (MSD) and specific heat capacity for systems of bulk Aluminium and Silicon. The interatomic potentials investigated are potentials trained using the ML models kernel ridge regression (KRR) and moment tensor potentials (MTPs). LÄS MER

  5. 4. Machine learning for the prediction of duplex stainless steel mechanical properties : Hardness evolution under low temperature aging

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Baptiste Giard; Sofia Karlsson; [2021]
    Nyckelord :Duplex Stainless Steel DSS; Machine Learning; Phase Separation; Me- chanical Properties; Alloying; Duplexa rostfria stål; Maskininlärning; Fasseparation; Mekaniska Egenskaper; Legering;

    Sammanfattning : Duplex stainless steels, DSS are stainless steels that consist of the two phases austenite and ferrite.  The DSS have superb properties and are widely used in industries such as nuclear power and in pressure vessels, pipes and in pipelines.  The use of DSS are limited due to embrittlement which occurs at temperatures from 250 to 550 oC.
