  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. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Pablo Martinez Cano; [2019]
    Keywords : LISA; PCB; temperature; passive; aluminum; aluminium;

    Abstract : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

  4. 3. Effect of dwell time on stress intensity factor of ferritic steel for steam turbine applications

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Ahmed Azeez; [2018]
    Keywords : ;

    Abstract : In the transition from conventional to green energy production resources, steam turbines are used to satisfy the lack of energy during peaks in the demand times and the limited access of renewable resources. This type of usage for steam turbines makes them operate on a flexible schedule, which leads to unpredictable issues related to shorter component life and faster crack propagation. READ MORE

  5. 4. Influence of In-vessel Pressure and Corium Melt Properties on Global Vessel Wall Failure of Nordic-type BWRs

    University essay from KTH/Kärnkraftssäkerhet

    Author : Andrei Goronovski; [2013]
    Keywords : Severe accident; Vessel failure; CRGT cooling; Thermo-Mechanical creep analysis;

    Abstract : The goal of the present study is to investigate the effect of different scenarios of core degradation in a Nordic-type BWR (boiling water reactor) on the reactor pressure vessel failure mode and timing. Specifically we consider the effects of (i) in-vessel pressure, (ii) melt properties. READ MORE

  6. 5. Weld head motion control of girth and tubular joint welding simulations in LS-DYNA

    University essay from Avd för maskinteknik

    Author : Andreas Segerstark; [2013]
    Keywords : FINITE ELEMENT ANALYSIS; LS-DYNA; LS-PREPOST; MOVING HEAT SOURCE; GIRT WELDING; TUBULAR JOINT WELDING.;

    Abstract : The basis for performing a thermo-mechanical staggered coupled heat source analysis of a welding simulation is implemented into LS-DYNA. In this report, three methods for initiating the heat source’s mechanical motion during girth and tubular joint welding are developed and evaluated. READ MORE
