Revealing the elusive role of water vapor in the oxidation behavior of a Mn-Si containing NiCr alloy at 950 °C
Source abstract
Abstract
Detailed nanoscale characterizations revealed the formation of a considerably higher fraction of SiO 2 particles in the external Cr 2O 3 layer on a NiCr alloy. In addition, atom probe tomography revealed substantially lower segregation of Mn at the Cr 2O 3 grain boundaries in wet air compared to dry air exposures, where the intriguing formation of Mn-rich clusters was observed in the Cr 2O 3 grains for the very first time. These findings provided additional evidence regarding the impact of distinct transport processes through the Cr 2O 3 layer on the resulting oxidation rates and subsurface alloy compositional changes.
