1. Microstructural design and optimization of Nickel-based superalloys for gas turbines
Master-uppsats, KTH/MaterialvetenskapSammanfattning : One of the main sources of energy in this modern world is the gas turbine. They reach extremely high working temperatures at peak capacity and hence require materials that can withstand the same. LÄS MER
2. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

3. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea
Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaperSammanfattning : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. LÄS MER
4. Aluminium Nitride-containing Steels for High-Temperature Low-Pressure Carburizing Processes
Master-uppsats, KTH/MaterialvetenskapSammanfattning : By increasing the temperature at which low-pressure carburizing is performed, the process time for production of case-hardened steels decrease but run a risk of abnormal grain growth occurring during carburizing. Particles present in the steel pin the grain boundaries and can prevent this growth depending on their size and volume fraction. LÄS MER
5. Modelling of precipitation in an Fe-C-Cr alloy
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Precipitation modelling is interesting from both an academic and an industrial point of view. Such modelling tools may be used in the field of integrated computational materials engineering (ICME) for design and optimization of material properties. LÄS MER
