摘要：

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 degrees 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 mu m to 30 mu m, as the temperature increased from 500 degrees C to 700 degrees 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.
