AbstractThe corrosion behavior of a Ni-16Mo-7Cr-4Fe alloy was investigated in a tellurium (Te) vapor atmosphere at 800 degrees C. Te was identified via electron probe microanalysis at the grain boundary regions of the corroded alloy. The morphology, chemical composition, and crystalline structure of those areas were characterized in a transmission electron microscope. Chromium tellurides were observed at both grain boundaries and intergranular carbide-matrix interfaces. Based on the results, the mechanism of intergranular Te corrosion and its possible correlation with intergranular cracking is discussed. (C) 2015 Elsevier Ltd. All rights reserved.
