1. Oxidation, Creep and Fatigue Synergies in Cast Materials for Exhaust Manifolds
Sammanfattning : The future development of engines of heavy-duty vehicles towards reduced CO2 emission will increase the exhaust gas temperature and render the exhaust atmosphere more corrosive. The current service material of exhaust gas components - a ferritic ductile cast iron called SiMo51 - will soon meet its upper-temperature limit. LÄS MER
2. Thermal Barrier Coatings for Diesel Engines
Sammanfattning : Reducing the heat losses in heavy-duty diesel engines is of importance for improving engine efficiency and reducing CO2 emissions. Depositing thermal barrier coatings (TBCs) onto engine components has been demonstrated to have great potential to reduce heat loss from the combustion chamber as well as from exhaust components.

3. Reliability, fatigue and mechanical characterization of lead-free solders for electronic packaging applications
Sammanfattning : The ever increasing amount of electronic waste, most of which ends up in landfills, has become a serious worldwide concern. In addition to this, the fact that Pb is highly toxic and harmful to humans has lead to the ban of this element from the electronics industry. LÄS MER

5. Thermal shock and thermal fatigue in ceramic materials
Sammanfattning : This thesis concerns thermal stress fracture in ceramicmaterials. The work describes a new technique for determiningthe thermal shock resistance of brittle materials as well asexperimental results and thermal stress simulations. LÄS MER
