Due to tightening environmental standards, the automotive industry is constantly trying to improvethe efficiency of the internal combustion engines in order to increase their fuel economy andreduce their carbon emissions. The main way to meet this goal on a turbocharged engine is toincrease the combustion temperature. This leads to increasing exhaust gas temperature andincreasing thermal loads on exhaust manifolds and turbine housings. These components beinguncooled, their maximum temperature is increasing and require better durability at hightemperature. The main objective of this thesis is to evaluate the durability of SiMo spheroidalgraphite iron (SGI) and 1.4826Nb cast stainless steel (CSS) at higher temperature than the actualmaximum o...
