1. 6. High Temperature Fatigue Behaviour of Austenitic Stainless Steel : Microstructural Evolution during Dwell-Fatigue and Thermomechanical Fatigue

   Författare :Hugo Wärner; Mattias Calmunger; Johan Moverare; Guocai Chai; Sten Johansson; Martina Zimmermann; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The global energy consumption is increasing and together with global warming from greenhouse gas emission, a need for more environmentally friendly energy production processes is created. Higher efficiency of biomass power plants can be achieved by increasing temperature and pressure in the boiler section, this would increase the generation of electricity along with the reduction in emission of greenhouse gases e.

4. 8. Development of a ferritic ductile cast iron for improved life in exhaust applications

   Författare :Madeleine Ekström; Stefan Jonsson; Pamela Henderson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material development; SiMo51; HK30; exhaust manifolds; high-temperature corrosion; high-temperature low-cycle fatigue;

   Sammanfattning : Due to coming emission legislations, the temperature is expected to increase in heavy-duty diesel engines, specifically in the hot-end of the exhaust system affecting components, such as exhaust- and turbo manifolds. Since the current material in the turbo manifold, a ductile cast iron named SiMo51, is operating close to its limits there is a need for material development in order to maintain a high durability of these components.

5. 9. Thermal and Mechanical Behaviors of High Temperature Coatings

   Författare :Kang Yuan; Lin Peng Ru; Xin-Hai Li; Sten Johansson; Yan-dong Wang; Nicolaie Markocsan; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With superior oxidation and corrosion resistance, metallic coatings (i.e. diffusion coatings and MCrAlX coatings) are widely used to protect hot components made of superalloys in turbine engines. LÄS MER

7. 10. On High-Temperature Behaviours of Heat Resistant Austenitic Alloys

   Författare :Mattias Calmunger; Sten Johansson; Guocai Chai; Johan Moverare; Hans-Jürgen Christ; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Advanced heat resistant materials are important to achieve the transition to long term sustainable power generation. The global increase in energy consumption and the global warming from greenhouse gas emissions create the need for more sustainable power generation processes. LÄS MER
