1. Neutron spectroscopy and computational studies of hydride-ion dynamics in oxide- and nitride-hydride materials
Sammanfattning : This thesis presents studies of the hydride-ion dynamics in the nitride- and oxidehydride materials Ca3CrN3H and BaTiO3-xHx (with x < 0.2). LÄS MER
2. Phase field modeling of flaw-induced hydride precipitation kinetics in metals
Sammanfattning : Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. LÄS MER
3. Ageing of the Nickel Metal Hydride Barrery
Sammanfattning : .... LÄS MER
4. Phase transformation and stability studies of the Zr-H system
Sammanfattning : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. Zirconium has a strong affinity for hydrogen, however, and if hydrogen concentration builds up, the material will gradually degrade. LÄS MER
5. In-situ phase studies of the Zr-H system
Sammanfattning : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. However, zirconium has strong affinity for hydrogen, which may lead to hydrogen concentration build-up over time during a corrosion reaction when exposed to water. LÄS MER
