  1. 1. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    Master-uppsats, KTH/Materialvetenskap

    Författare :Helena Ek Jendrny; [2023]
    Nyckelord :AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Sammanfattning : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. LÄS MER

  3. 2. Lithium iron phosphate batteries for energy shifting

    Master-uppsats, KTH/Kemiteknik

    Författare :Helena Glisén; [2023]
    Nyckelord :Lithium iron phosphate batteries; energy shifting; electricty storage; investment calculation; electrification; Litium-järnfosfatbatterier; kortvarig energilagring; ellagring; investeringskalkyl; elektrifiering;

    Sammanfattning : Elanvändningen i Sverige förväntas fördubblas till 2045 på grund av ökad elektrifiering av det svenska samhället. För att ställa om till ett elsystem som är beroende av mer förnyelsebara elproduktionsslag föreslår Svenska kraftnät (2021) att Sverige kommer att behöva öka sin flexibilitet i elnätet. LÄS MER

  4. 3. Study and optimization of a hexacopter's composite structure

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Helena Delmotte; [2023]
