21. On the Residual Stresses and Microstructure Formation of Aluminum-Silicon Cast Alloys
Abstract : Cast aluminum-silicon alloys are being increasingly used in automotive and aerospace industries for critical structure applications because of their excellent castability, low density, acceptable mechanical properties and low cost. Different casting and heat treatment parameters largely affect the microstructure and residual stress of the components, which in turn, has a great impact on their mechanical properties. READ MORE

23. Life Prediction and Mechanical Behavior of Thermal Barrier Coatings
Abstract : Delamination and spallation of thermal barrier coating (TBC) systems, used in hot parts of gas turbines, have been studied with respect to thermal fatigue. TBCs with and without pre-existing cracks were investigated. Thermal shock tests were performed until coating spallation. READ MORE

24. Thermal Cycling, Creep- and Tensile Testing of Cast Exhaust Materials at Elevated Temperatures
Abstract : An exhaust manifold of a truck engine is subjected to tough conditions. As the truck is started, operated and shut down, it becomes subjected to thermal cycling up to around 800°C. At such high temperatures, corrosion, fatigue and creep are active degradation mechanisms. READ MORE

25. Light scattering for analysis of thermal stress induced deformation in thin metal films
Abstract : Today, thin film based devices are found in a wide field of applications. The main reasons are that thin film technology enables access to unique physical properties and possibilities to miniaturize devices. Thin film devices are generally described in terms such as electrical, optical and magnetical properties. READ MORE
