1. 1. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

   Master-uppsats, KTH/Materialvetenskap

   Författare :Felicia Larsson; [2023]
   Nyckelord :;

   Sammanfattning : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. LÄS MER

3. 2. 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

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

   Master-uppsats, KTH/Materialvetenskap

   Författare :Simone Quintè; [2023]
   Nyckelord :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;

   Sammanfattning : 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. 4. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

7. 5. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

   Master-uppsats, KTH/Materialvetenskap

   Författare :Mochen Li; [2023]
   Nyckelord :Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

   Sammanfattning : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. LÄS MER
