Popis: The corrosion resistance of the vanadium alloys, V-1.86 Ga, V-3.4 Ga-0.62 Si, and V-4.81 Ti-4.82 Cr, in high-purity liquid lithium containing less than 1 × 10−3 wt % of carbon and nitrogen was investigated as compared to pure vanadium. The corrosion tests were carried out in the static isothermal conditions at a temperature of 600°C during 400 h. It was established that vanadium and its alloys are almost insoluble in lithium, and a basic mechanism of their interaction with liquid metal in this case is the transfer of oxygen from the materials into lithium. Traces of the corrosion effect on the surface of the materials after their exposure to lithium were also found, resulting in the appearance of grain boundaries and slip lines.
