Estimation of the effect of molybdenum on chemical and electrochemical stability of iron-based alloys

The E-pH diagram of Mo-H2O system is refined. A cross-section of the Fe-Mo-O phase diagram at 25degreesC is constructed. The E-pH diagrams for the systems Fe-Mo-H2O and alloy X17Hl3M2-H2O are cal culated. Thermodynamic aspect of the effect of molybdenum on chemical and electrochemical stability of iron alloys is discussed.
