1. 1. ADDITIVE MANUFACTURING OF PURE COPPER USING ELECTRON BEAM MELTING (EBM)

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Prithiv Kumar Chinnappan; Vishal Shanmugam; [2022]
   Nyckelord :Additive Manufacturing; Electron Beam Melting; Pure Copper; Process Optimisation.; Additiv tillverkning; Elektronstrålesmältning; Ren koppar; Processoptimering.;

   Sammanfattning : Pure copper (Cu) has the properties of high optical reflectivity and surface tarnishing as well as excellent thermal and electrical conductivity. Accordingly, laser-based additive manufacturing (AM) techniques confront various difficulties to produce thismaterial. LÄS MER

3. 2. Effect of iron redox state on crystallization behaviour of Fayalite slags

   Master-uppsats, KTH/Materialvetenskap

   Författare :Paolo Mai; [2020]
   Nyckelord :Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

   Sammanfattning : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. LÄS MER
