  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. Investigation of non-metallic inclusions and chip properties in Cu-based alloys by numerical analysis

    University essay from KTH/Materialvetenskap

    Author : Ousmane El Hamid; Mattias Eriksson; [2022]
    Keywords : ;

    Abstract : Analysis of the macrostructure of metallic alloys is of utmost importance as there is a direct correlation on the physical properties and some features of the structures. This is true for copper based alloys and the non-metallic inclusions (NMI) that are enclosed in their structure. READ MORE

  4. 3. Evaluation of a novel method to investigate diffusion between copper-zinc alloys and cemented carbides

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : André Larsson; [2022]
    Keywords : Diffusion; Brass; Copper alloys; Copper zinc alloys; Wear; Cemented carbide; Diffusion couple;

    Abstract : When slow wear mechanisms are studied it is important to examine slower processes, such as diffusion. Such processes can have a significant impact over time and can cause other phases to form, which can have a large effect on the wear. READ MORE

  5. 4. Corrosion behaviour of new lead-free brass alloys in aqueous copper (II) chloride

    University essay from KTH/Kemi

    Author : Oliver Freiholtz; [2021]
    Keywords : lead-free brass; corrosion; dezincification; copper II chloride; electrochemistry; blyfri mässing; korrosion; avzinkning; koppar II klorid; elektrokemi;

    Abstract : På grund av nya riktlinjer för användning av mässing i kontakt med dricksvatten har nya blyfria mässingslegeringar utvecklats. Det är därför av stort intresse att undersöka deras korrosionsegenskaper, såsom avzinkningshärdighet. READ MORE
