  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

  4. 3. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  5. 4. Casting Simulation of Air Disc Brake

    University essay from Lunds universitet/Industriell Produktion

    Author : Shankar Vijaykumar Patil; Shivakumar Malagi; [2021]
    Keywords : Casting Simulation; Air Disc Brakes; Casting Defects; Residual Stresses; Parameter Mapping; Novacast; Technology and Engineering;

    Abstract : Casting Simulation software which have become popular tools for modern metal casting industries and foundries, are on the verge of becoming the epicenter of virtually replicating the process of casting and its optimization. Our aim is to combine and compare results from Casting simulation and FEA of Air Disk Brake, utilize these results to map parameters that affect the quality of Cast components to Structural analysis.
