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. Optimization of alloys recovery in steel scrap sorting : Technological, economic and environmental considerations for a better chromium, nickel and molybdenum recovery in steel scrap
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Today’s steelmaking industry is highly dependent on steel scrap supply. In order to reduce the greenhouse gas emissions (GHGs) deriving from the steel industry, it is of utmost importance to ensure that high percentages of steel scrap are recycled, reducing the reliance on the traditional ore-based steelmaking, which is significantly more environmentally impactful.

3. 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
4. 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
5. 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
