"Thermogravimetry and in-situ mass spectrometry at high temperature compared to thermochemical modelling - The weight loss during selective decarburisation at 800°C";
Corrosion Science, 78 (2014), 188 - 192.



English abstract:
The in-situ mass spectrometry detection of volatile species during high temperature corrosion processes, exemplified by decarburisation of plain carbon steel, will be presented. Without influencing the thermobalance signal, changes of the gas composition can be measured by introducing a small quartz capillary into the reaction chamber in close proximity to the sample surface.

Experiments with the eutectoid composition Fe, 0.8wt-%C have been chosen intentionally as this alloy represents one of the most intensely studied compositions in steel research. This allows good verification with commonly accepted knowledge. Furthermore, comparison between experimental observations and theoretical simulations will be given and critically discussed.
