  1. 1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

    University essay from KTH/Materialvetenskap

    Author : Josefin Mvele Svensson; [2024]
    Keywords : Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

    Abstract : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and  the  content  of  non-metallic  inclusions  (NMI).  Achieving  cleanliness  is a  gradual  process  where all  the  steps  of  the  production  process  are  inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

  3. 2. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes

    University essay from KTH/Materialvetenskap

    Author : Paulo Urrea Molina; [2023]
    Keywords : ;

    Abstract : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).

  4. 3. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels

    University essay from KTH/Materialvetenskap

    Author : Milou Göransson; [2023]
    Keywords : Clean steel; Ultraclean steel; Longitudinal turning; Cemented carbide cutting tool; Chemical vapor deposition coating; Machinability; Tool wear; Non-metallic inclusions; Rent stål; Ultrarent stål; Längdsvarvning; Hårdmetall skärverktyg; Kemisk ångdeponering beläggning; Bearbetningsbarhet; Verktygsslitage; Icke-metalliska inneslutningar.;

    Abstract : Application of clean and ultraclean steels have shown to provide favourable mechanical properties for bearings and transmission components, specifically regarding fatigue performance, compared to conventional steel grades. Clean steels are characterized by containing a very low level of non-metallic inclusions. READ MORE

  5. 4. Investigation of Non-Metallic Inclusions in Inconel 718 by Using Conventional Cross-Sectioned (CS) Method and Experimental Extraction Metal-Surfaced (MS) Method

    University essay from KTH/Materialvetenskap

    Author : Mehreen Baig; [2022]
    Keywords : ;

    Abstract : Inconel 718 is a nickel-based alloy, predominantly used in the oil and gas industry, in aircraft engines as well as in gas turbine engines. It provides exceptional properties like high strength, creep resistance, corrosion resistance and long fatigue life at high temperatures as well as in cryogenic environments. READ MORE

  6. 5. Investigations of Large Size Non-Metallic Inclusions in the Nickel-based alloy Inconel 718

    University essay from KTH/Materialvetenskap

    Author : Yuehui Ma; Wardah Saleem; [2022]
    Keywords : ;

    Abstract : Inclusions of different types are present in all steels. How dangerous these are for the properties of the material depends on their chemical composition and the manufacturing process. READ MORE
