    The corrosion tests of V-4Ti-4Cr alloy (NIFS HEAT 2) tensile samples were carried out in static liquid Pb with ~10-9 mass% dissolved oxygen at 500 and 700 ◦C for 1000 h. A clear intergranular corrosion attack was observed on the surface of the samples. Corrosion losses increase ten times, from around 3.0 μm to 30 μm, as the temperature increased from 500 ◦C to 700 ◦C, respectively. The alloy remained ductile after the tests at both temperatures. A phenomenology of interaction processes in Pb[O]-V[Cr,Ti] system is discussed.
