The analysis of microstructures and phase transformations is key to tuning and predicting their properties and lifespan for different application scenarios. This applies particularly to superalloys and intermetallics used for aero engines which we have thus chosen to highlight in this newsletter edition.
Aviation has a very high impact on greenhouse gas emissions. In order to tackle CO2 emissions, it has become necessary to increase the operational temperature of aircraft engines, which will result in a higher efficiency and reduced CO2 emissions.
Intermetallic phases – intermetallics for short – are phases which have different crystallographic structures than the elements they are composed of. Compared to conventional alloys with a solid solution matrix, additional chemical bonding in the intermetallics usually results in higher melting points...
