1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

2. 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
3. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines
Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskapSammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER
4. An analytical method for quickly evaluating the performances of refractory alloys in sCO2 Brayton cycle applications
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : A rapid and effective analytical method has been developed to assess the performance of structural materials in sCO2 power cycle applications. This method combines a conjugate heat transfer model, considering constant heat flux boundary conditions, with a corresponding mechanical model. LÄS MER
5. An overview of the development and potential of ceramic materials for use in micro gas turbines
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This paper presents an analysis of the potential of Micro Gas Turbines (MGT) with regards to performance, economic and durability considerations. The performance potential was assessed by calculating the cycle efficiency based on the Brayton cycle and the mechanical efficiency of the expansion turbine. LÄS MER
