摘要：

Analytical electron microscopy and Auger spectroscopy were used to study the amount and distribution of Fe, Cr and S impurities in the Al(2)O(3) scale grown on an FeCrAl alloy. Segregations of Fe on grain boundaries and S on internal void surfaces were found, and a mechanism of intragranular void formation in Al(2)O(3) is proposed. (C) 2003 Acta Materialia Inc.
