1. 1. Exploratory synthesis and characterisation in the Gd-Au-Si-system : A quest for quasicrystals

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

   Författare :Hanna Ohlin; [2017]
   Nyckelord :quasicrystals; approximants; Gd-Au-Si-system;

   Sammanfattning : The field of crystallography has recently been expanded to include the science of quasicrystals, crystalline structures lacking unit cells and conventional periodicity. This resulted in a paradigm shift in the field, opening up for a whole new branch on the subject of structural chemistry. LÄS MER

3. 2. PROCESSUTVECKLING FÖR JÄRNBASERADE HÅRDMAGNETISKA PULVER UTAN SÄLLSYNTA JORDARTSMETALLER

   Master-uppsats, Lunds universitet/Materialteknik

   Författare :Per-Olof Andersson; [2014]
   Nyckelord :Crystalline metals; Magnetic materials; Hard magnetic materials; Electro-magnetic applications; Single crystalline powder; Powder metallurgy; Fe2B; FeB; Water atomization; Gas Water atomization; non-RE hard magnetic material.; Technology and Engineering;

   Sammanfattning : An experimental study was performed, aimed at finding a way to produce single crystalline powder of pure (Fe0.7Co0.3)2B with a particle size of 100-200nm. This was done with the ultimate goal of producing a hard magnetic ferrite powder for powder metallurgical production of permanent magnets. LÄS MER
