1. Crack growth in single crystal gas turbine blade alloys under service-like conditions
Sammanfattning : This work concerns the fatigue crack growth behaviour of nickel base single crystal superalloys. The main industrial application of this class of materials is in gas turbine blades, where the ability to withstand severe mechanical loading in combination with high temperatures is required. LÄS MER
2. Initiation and early crack growth in VHCF of stainless steels : Experimental and theoretical analysis
Sammanfattning : Mechanical fatigue is a failure phenomenon that occurs due to repeated application of mechanical loads. Very High Cycle Fatigue (VHCF) is considered as the domain of fatigue life greater than 10 million load cycles. LÄS MER
3. 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.
