  1. 1. Thermodynamic modelling of the copper-zinc-tin ternary system : A study towards lead-free brass

    University essay from KTH/Materialvetenskap

    Author : Caterina Radogna; [2023]
    Keywords : Brass-based alloys; Lead-free brass; Calphad; Thermo-Calc; Thermodynamic description; Mässingsbaserade legeringar; Blyfri mässing; Calphad; Thermo-Calc; Termodynamisk beskrivning;

    Abstract : Lead (Pb) is frequently used as an alloying element in brass to enhance machinability and castability. However, this element poses a significant risk to human health and the environment. The 2021 revision of the Drinking Water Directive imposed stricter limits on Pb content in brass, encouraging the development of lead-free brass. READ MORE

  3. 2. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

    University essay from Lunds universitet/Industriell Produktion

    Author : Christian Jaunviksna; [2023]
    Keywords : Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

    Abstract : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. READ MORE

  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

    University essay from Lunds universitet/Industriell Produktion

    Author : Andreas Söderholm; [2021]
    Keywords : Grey cast iron; hard inclusions; tool wear; machinability; graphite structure.; Technology and Engineering;

    Abstract : Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. READ MORE

  6. 5. Changes in Gray cast iron over the last century-An initial study

    University essay from Lunds universitet/Industriell Produktion

    Author : Puneeth Kumar Shivarudrappa; [2021]
    Keywords : Gray cast iron; age strengthening; and machinability.; Technology and Engineering;

    Abstract : This thesis report summarizes the research on the cold aging of gray cast iron samples dating back 100 years, and how researchers looked at the phase history and amount of impurities and trace metals generated by recycling. Initially, the topic of the thesis is introduced, with an explanation and general information on gray cast iron. READ MORE
