22. 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
23. Modelling of Crack Growth in Single-Crystal Nickel-Base Superalloys
Sammanfattning : This dissertation was produced at the Division of Solid Mechanics at Linköping University and is part of a research project, which comprises modelling, microstructure investigations and material testing of cast nickel-base superalloys. The main objective of this work was to deepen the understanding of the fracture behaviour of single-crystal nickel-base superalloys and to develop a model to predict the fatigue crack growth behaviour.

24. Modelling Aspects in Forming and Welding of Nickel-Base Superalloys
Sammanfattning : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry because of major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the weight of vehicles while increasing the efficiency of the engine. LÄS MER
25. Processability of Laser Powder Bed Fusion of Alloy 247LC-Influence of process parameters on microstructure and defects
Sammanfattning : This thesis is about laser powder bed fusion (L-PBF) of the nickel-basedsuperalloy Alloy 247LC. Alloy 247LC is mainly used in gas turbine blades and processing the blades with L-PBF may confer performance advantage over the blades manufactured with conventional methods. LÄS MER
