  1. 1. Investigation of Methods to Improve PZT Sol-Gel Deposition Process for Energy Harvesting Applications

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Mikael Granberg; [2022]
    Nyckelord :PZT; sol-gel; self-polarization; seed layer; titanium oxidation; PZT; sol-gel; självpolarisering; seedlager; titanoxidering;

    Sammanfattning : The purpose of this work was to investigate ways to modify Silex sol-gel deposition of PZT (PbZrxTi(1-x)O3, Lead Zirconate Titanate) in order to improve its properties for energy harvesting applications. A number of methods to improve the figure of merit for energy harvesting (FOM= e312/ε), cause self-polarization, increase lifetime, reduce cost, increase throughput or simplify processing were tested.

  3. 2. Effect of oxygen concentration in build chamber during laser metal deposition of Ti-64 wire

    Master-uppsats, KTH/Materialvetenskap

    Författare :Eyvind Engblom; [2018]
    Nyckelord :additive manufacturing; laser metal deposition; alpha-case; titanium; wire;

    Sammanfattning : Additive manufacturing of titanium and other metals is a rapidly growing field that could potentially improve component manufacturing through optimization of geometries, less material waste and fewer process steps. Although powder-based additive manufacturing processes have so far been predominant, methods using a wire as feedstock has gained popularity due to faster deposition rates and lower porosity in deposited material.

  4. 3. Characterizing magnetic susceptibility and remanent magnetization of magnetite and hematite rich drill-core samples at Blötberget

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Andreas Bjork; [2018]
    Nyckelord :Verwey; Morin; Curie; Néel; magnetite; hematite; alteration; iron-ore; quality control; kappabridge; hysteresis; susceptibility; anisotropy; Verwey; Morin; Curie; Néel; magnetit; hematit; oxidation; järnmalm; kvalitetskontroll; kappabridge; hysteresis; susceptibilitet; anisotropi;

    Sammanfattning : Laboratory magnetic measurements are used to develop a methodology to characterize the Kiruna-type Rare Earth Elements (REE) bearing apatite iron-oxide deposits at Blötberget in central Sweden. This high-grade ore deposit is known to have sharp boundaries between lens shaped main ore bodies of magnetite-rich ore, and a complex hematite-rich ore associated with pegmatites and skarn formation.

  5. 4. Towards a bottle weight reduction - Evaluation in a selected milk plant in the United Kingdom

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Elena Ascension Baixauli Marin; [2017]
    Nyckelord :pasteurised milk; milk packaging; HDPE bottles; Light weight; PET bottles; Technology and Engineering;

    Sammanfattning : The United Kingdom is one of the biggest milk producers in the world. The dairy market is a competitive industry where cost is a driving force. Milk is considered a day-to-day product in this country, packaged primarily in HPDE bottles. The need for a cost effective product is driving companies to seek for alternative packaging solutions.

  7. 5. Evaluation of Heat Treatments for the Nickel-Based Superalloy Haynes® 282® Manufactured by Selective Laser Melting : A Study Based on Microstructural Examinations and Mechanical Testing

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Adam Selldén; [2017]
    Nyckelord :;

    Sammanfattning : Nickel-based superalloys have a wide range of applications, mainly in gas turbines for power generation and aircraft propulsion. They are superior to competing alloys in maintaining excellent mechanical properties for extended durations at extreme temperatures and loads, all while resisting corrosion and oxidation. LÄS MER
