1. 1. 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.

3. 2. Precipitation during Tempering of Martensite in Fe-Cr-C alloys

   Master-uppsats, KTH/Materialvetenskap

   Författare :Chanachon Techaboonanek; [2012]
   Nyckelord :precipitation; microstructure; tempered martensite; Fe-C-Cr alloys; carbide; simulation;

   Sammanfattning : The martensite structure is the most important microstructure in tool steel due to its high hardness. However, a lack of ductility is the major drawback. In order to improve the ductility and still maintaining a suitable hardness a tempering process is needed. LÄS MER
