| Abstract |
New types of two-dimensional thermodynamic stability diagrams were presented to predict high temperature corrosion behavior of multi-component alloys in mixed oxidant environments. The new stability diagrams were constructed by computer-assisted phase equilibria calculations of the multi-component reacting system. The usefulness of the new stability diagrams is discussed with the Fe-Cr alloys in oxidizing-chloridizing environments. The new stability diagrams can provide valuable information on the internal oxidation behavior of alloys and the stability of ternary phases such as FeCr₂O₄, which cannot be obtained from the conventional stability diagrams. Using reaction paths on the new stability diagrams, more mechanistic predictions can be made for the mixed corrosion behavior of alloys. |
