1. Creep Behavior of High Temperature Cast Materials for Exhaust Applications
Sammanfattning : This thesis focuses on creep of four cast materials intended for exhaust manifolds in heavy-duty truck engines. Two of the materials are ferritic ductile cast irons, SiMo51 and SiMo1000, one is an austenitic ductile cast iron, D5S, and another one is an austenitic cast steel, HK30. LÄS MER
2. High temperature performance of materials for future power plants
Sammanfattning : Increasing energy demand leads to two crucial problems for the whole society. One is the economic cost and the other is the pollution of the environment, especially CO2 emissions. Despite efforts to adopt renewable energy sources, fossil fuels will continue to dominate. LÄS MER
3. Influence of Segregants on Creep Fracture in Powder Metallurgical Martensitic Stainless Steel
Sammanfattning : This thesis deals with the behaviour of segregants in Powder Metallurgical (PM) 10%Cr steel and their impact on creep fracture. Particular interest is taken in determining the reaction products involved in creep cavitation and how these are connected to the powder surface reactions during the gas atomisation and consolidation (hot isostatic pressing).

4. Fundamental models and testing of creep in copper
Sammanfattning : Many sustainable technologies for energy production, for example, generation IV nuclear system, demand the use of materials operating at elevated temperatures for long duration of up to 60 years. Requirements that are even more stringent are found for creep exposed copper canisters for disposal of spent nuclear waste. LÄS MER
5. Deformation and Fracture of Ceramics and Ceramic Composites
Sammanfattning : An understanding of the deformation and fracture behaviour of ceramic materials is of considerable importance in the development of ceramics as reliable structural materials. Of particular interest is how such behaviour is influenced by the microstructure, for example in multiphase materials such as composites. LÄS MER
