  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

    Kandidat-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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. Precipitation analysis in bearing steel Hybrid 60

    Master-uppsats, KTH/Materialvetenskap

    Författare :Rebecca Rosén; [2023]
    Nyckelord :martensitic steel; secondary hardening; precipitation; PRISMA; martensitiskt stål; sekundärhärdning; utskiljning; PRISMA;

    Sammanfattning : New materials are always being developed to get the best properties possible where needed. The way to create these materials and test them is also developing. When it comes to high-strength steels, a martensitic microstructure is a common choice. LÄS MER

  4. 3. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Atharva Kotasthane; [2023]
    Nyckelord :Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

    Sammanfattning : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. LÄS MER

  5. 4. Assessment of a Historical Aluminium alloy : A study on Fritzi metal along with an analysis on the properties and casting trials

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Shawnee Hussain; Emil Johansson; [2021]
    Nyckelord :;

    Sammanfattning : During World War I, Otto Meyer invented the alloy Fritzi metal, and the composition died with him. However,  there  are  descriptions  of  the  alloy's properties.  Previously,  an  attempt  to  identify  the composition  was  made, resulting  in  simulated  properties  that  did not match those described.

  7. 5. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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. LÄS MER
