Elucidation of orientation relations between Fe-Cr alloys and corrosion products after high temperature SO2 corrosion
Source abstract
Abstract
The early stages of corrosion of Fe-Cr-model alloys (2 and 9 % Cr) were investigated after exposure at 650 degrees C in 0.5 % SO2 containing gas by electron backscattered diffraction (EBSD) and transmission electron microscopy (TEM). The impact of the grain orientation of the base alloy on the orientation relations of the corrosion products is presented. After 2 min - 5 min exposure the formation of a multi-layered corrosion zone was discovered. A clear orientation relationship between ferrite and the (Fe,Cr)(3)O-4 spinel could be demonstrated. The obtained results show the importance of the grain orientation on oxidation resistance.
