  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. 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

  4. 3. Microstructure-corrosion interrelations in new low-lead and lead-free brass alloys

    University essay from KTH/Materialvetenskap

    Author : Emil Stålnacke; [2017]
    Keywords : Brass; dezincification; annealing; detrimental phases; heat treatment; microstructure;

    Abstract : In new low-lead and lead-free brass alloys, it is not understood how the corrosion properties,such as dezincification, are related to material composition as well as annealing temperatureand duration. This study aims to fill this knowledge gap by mapping sixteen annealingconditions and three different brass alloy compositions to their respective microstructure anddezincification performance.

  5. 4. Aluminium alloys ability to catalyse the oxidation of biodiesel : Development of a procedure to test alloys

    University essay from KTH/Kraft- och värmeteknologi

    Author : Ivan Khudur; [2017]
    Keywords : Accelerated aging; aluminium; aluminium alloys; biodiesel; copper; oxidation stability; RME; test method;

    Abstract : Biodiesel is a renewable and biodegradable fuel that has the possibility to replace conventional diesel fuel and reduce the environmental pollution. Despite its environmental benefits, it has been shown to cause damage to the vehicle engines, due to its oxidative properties. READ MORE
