1. Evolution of microstructure and nanoscale chemistry of Zircaloy-2-type alloys during nuclear reactor operation
Sammanfattning : Zirconium alloys are used as fuel cladding tubes in nuclear reactors. During reactor operation, these alloys are degraded by corrosion, hydrogen pickup (HPU), and radiation-induced growth, processes influenced by the alloying elements. LÄS MER
2. Atom probe tomography of Zircaloy-2 exposed to boiling water reactor operation
Sammanfattning : Zirconium alloys are used as cladding tubes for the fuel in nuclear reactors. In boiling water reactors (BWRs), the alloy Zircaloy-2, which contains the alloying elements Sn, Fe, Cr, Ni, and O, is commonly used. LÄS MER
3. Modelling the system Cr-Fe-Ni-Te via the CALPHAD method, DFT and experiments : for fast nuclear reactor applications
Sammanfattning : In the pursuit of safer, more environmentally friendly and sustainable forms of energy production for our ever growing demands, a type of nuclear reactor cooled by liquid metal instead of water is under development. Specific to this type of reactor are special forms of corrosion of the material that encapsulates the fuel pins in the reactor core, called Fuel-Clad Chemical Interaction (FCCI) or Fission Product-induced Liquid Metal Embrittlement (FPLME).

4. Microstructure and hydrogen embrittlement of additively manufactured Ti-6Al-4V
Sammanfattning : The work of this doctoral thesis has been performed between the 24th of August 2015 to the 6th of September 2019. The general purpose of this work has been to increase the knowledge of additively manufactured Ti-6Al-4V when it comes to microstructure, texture and hydrogen embrittlement. LÄS MER
5. Binary mixtures and cationic modification of protic ionic liquids. Local structure and transport properties
Sammanfattning : Protic ionic liquids are a subclass of ionic liquids, which in many cases are obtained by mixing an equimolar amount of Brønsted acid and base. Protic ionic liquids possess an exchangeable proton that gives them distinct features, e.g. LÄS MER
