Studies were carried out on corrosion behavior of Fe-Cr-Al-base model alloys during their exposure to oxygen-containing lead in the temperature range 400-600°C. A map of the alumina stability domain for this temperature range was drawn in Fe-Cr-Al ternary diagrams and the type of alumina polymorph, formed at different temperatures, was determined. Fretting enhanced corrosion of selected fuel clad materials like 15-15Ti, T91 and aluminum surface alloyed steel is discussed and fretting rates of materials in liquid lead as function of temperature, load and amplitude are given.
