  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. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    University essay from KTH/Materialvetenskap

    Author : Helena Ek Jendrny; [2023]
    Keywords : AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Abstract : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. READ MORE

  4. 3. The solar abundance of beryllium : constraining the solar problem via non-LTE modelling

    University essay from

    Author : Daria Ogneva; [2023]
    Keywords : atomic processes; radiative transfer; abundance;

    Abstract : Accurately determining the solar abundance of beryllium is a key to calibrate transport processes at the base of convective zone, which in turn is an improvement upon existing solar models and general understanding of the physical processes within the Sun. To determine an abundance, assumptions about the solar atmosphere must be made. READ MORE

  5. 4. Additively Manufactured Rare Earth Free Permanent Magnets

    University essay from Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Oorganisk kemi

    Author : Himesha Abenayake; [2023]
    Keywords : additive manufacturing; MnAl; MnAl C ; rare earth free permanent magnets; selective laser melting; SLM; MnAl-based permanent magnets;

    Abstract : It’s well known that MnAl(C) material consists of a metastable phase (τ) with promising ferromagnetic properties, produced either by controlled cooling from the high-temperature hexagonal ε-phase or rapid cooling that freezes the ε-phase followed by low-temperature annealing. Due to the high cooling rates involved, additive manufacturing (AM) especially selective laser melting (SLM), has been identified as a possible method to retain the high-temperature ε-phase, hence containing a potential capacity to produce permanent magnets upon low-temperature annealing.

  6. 5. Neural Network Based Control Design for a Unicycle System

    University essay from Linköpings universitet/Reglerteknik

    Author : Axel Ek; [2023]
    Keywords : ;

    Abstract : Physics-based models of dynamical systems can take a lot of time and be hard to derive, and there will always be some effect that was not added to the calculations, like aerodynamic-, gyroscopic- or frictional- effects. Calculating all these effects takes time and a lot of knowledge of the system dynamics. READ MORE
