  1. 1. Effect of Trace Elements on the Particle Size of Magnesium Silicide in Aluminium Extrusion : The Use of Thermo-Calc and DICTRA in order to Produce Aluminium more Efficiently

    University essay from KTH/Materialvetenskap

    Author : Gustav Boustedt; Johan Alexander Valentin Nygren; Gustav Strandgård; [2023]
    Keywords : Thermo-Calc; DICTRA; simulations; EN AW 6082; extrusion; particle precipitation; Mg2Si; sustainable; trace elements; aluminium;

    Abstract : This project is a feasibility study for Hydro Extrusion Sweden AB, a company that produces extruded aluminium profiles. The main purpose of this project was to analyse the difference of Mg2Si particle sizes in aluminium alloys when varying parameters, such as cooling rate and composition, in aluminium extrusion, particularly the EN AW 6082 alloy.

  3. 2. Coupled flux nucleation model applied to the metallic glass AMZ4

    University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : Mattias Tidefelt; [2021]
    Keywords : Material science; numerical modeling; metallic glasses; classical nucleation theory;

    Abstract : Additive manufacturing (AM), also known as 3D-printing, has made it possible to produce components made of bulk metallic glass (BMG) which have remarkable properties compared to parts made of conventional alloys. A metallic glass is a metastable noncrystalline alloy that form if a melt is quenched with a sufficient cooling rate. READ MORE

  4. 3. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing

    University essay from KTH/Materialvetenskap

    Author : Julia Sjöström; [2020]
    Keywords : Maraging steel; selective laser melting; temperature evolution; macro-scale modelling; segregation; ICME.;

    Abstract : Additive manufacturing methods for steel are competing against commercial production in an increasing pace. The geometry freedom together with the high strength and toughness due to extreme cooling rates make this method viable to use for high-performance components. The desirable material properties originate from the ultrafine grain structures. READ MORE

  5. 4. The Effect of Cooling Rate on Sintered Cemented Carbides

    University essay from KTH/Materialvetenskap

    Author : Lina Berglund; [2020]
    Keywords : Sintering; Cooling rate; Cemented Carbide; Sintering; Coercivity; Contiguity; Sintring; Kylhastighet; Hårdmetaller; Koercivitet; Kontiguitet;

    Abstract : Magnetic measurements are useful tools for quality control of cemented carbides. Previous work at Sandvik Mining and Rock Technology has shown that the coercivity increases with increased cooling rate during sintering for a specific grade. READ MORE

  6. 5. The Effect of Solidification time and Cooling rate on the Ultimate tensile Strength of Grey Cast Iron.

    University essay from KTH/Materialteknologi

    Author : Dinesh Sundaram; [2018]
    Keywords : Lamellar graphite iron; tensile properties; pearlitic properties; cooling rate; solidification time; Magmasoft.;

    Abstract : Tensile strength modelling is usually done to predict the mechanical properties of lamellargraphite iron considering microstructural features. This work attempts to create a simplifiedmodel incorporating cooling rate and solidification time without considering themicrostructural features. READ MORE
