  1. 11. Fatigue strength assessment of post weld improved welded joints

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Veronika Nerbe; [2023]
    Keywords : Mechanics; solid mechanics; lightweight structures; hfmi; weld; Mekanik; hållfasthetslära; lättkonstruktioner; hfmi; svets;

    Abstract : In this thesis work a literature survey is done to collect published data for T-welded joints with a thickness of 5-12 mm, produced in high strength steel and treated with HFMI. In addition to this, large structures are researched. READ MORE

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

    University essay from KTH/Materialvetenskap

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

    Abstract : 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. READ MORE

  4. 13. Optimization of alloys recovery in steel scrap sorting : Technological, economic and environmental considerations for a better chromium, nickel and molybdenum recovery in steel scrap

    University essay from KTH/Materialvetenskap

    Author : Simone Quintè; [2023]
    Keywords : Steel scrap sorting; stainless steel; Chromium; Nickel; Molybdenum; alloys recovery; Laser Induced Breakdown Spectroscopy; revenue modeling; CO2 emissions modeling; Stålskrot Sortering; rostfritt stål; Krom; Nickel; Molybden; återvinning av legeringar; Laserinducerad nedbrytningsspektroskopi; intäktsmodellering; Modellering av CO2-utsläpp;

    Abstract : Today’s steelmaking industry is highly dependent on steel scrap supply. In order to reduce the greenhouse gas emissions (GHGs) deriving from the steel industry, it is of utmost importance to ensure that high percentages of steel scrap are recycled, reducing the reliance on the traditional ore-based steelmaking, which is significantly more environmentally impactful.

  5. 14. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    University essay from KTH/Materialvetenskap

    Author : Christopher Hallén; Marcus Johansson Storne; [2023]
    Keywords : ;

    Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

  6. 15. Integrating biomass gasification with electric arc furnace steel making

    University essay from KTH/Energiprocesser

    Author : Filippa Andersson; [2023]
    Keywords : Electric arc furnace; EAF off-gas; gasification; CCU; process integration; Ljusbågsugn avgasrök; ljusbågsugn; förgasning; kolavskiljning; process integration;

    Abstract : Utsläppen av växthusgaser ökar över hela världen och nya tekniker används för att minska utsläppen. 7% av utsläppen kommer från stålsektorn. 25% av världens stålproduktion görs via återvinningstekniken ljusbågsugn. Genom återvinningsprocessen släpps det ut 500kg CO2 per ton producerat flytande stål. READ MORE
