The corrosion resistance of vanadium alloys (V- 1,86Ga, V- 3,4Ga- 0,62 Si, V- 4,81Ti- 4,82Cr) in the liquid high purity lithium (carbon and nitrogen less than 1 • 10 -3 wt.%, oxygen ~ 0.02-0.03 wt.%)  in comparison with the pure vanadium has been studied. Corrosion tests were carried out in the static isothermal conditions at the temperature of 600 °C during 400 hours. It was established that vanadium and its alloys are practically insoluble when exposed to lithium,  oxygen transfer from  materials into the lithium being main mechanism of their interaction with the liquid metal in this case. Traces of corrosion effect on the surface morphology after exposure to lithium were also found, resulting in the appearance of grain boundaries and slip lines.The corrosion resistance of vanadium alloys (V- 1,86Ga, V- 3,4Ga- 0,62 Si, V- 4,81Ti- 4,82Cr) in the liquid high purity lithium (carbon and nitrogen less than 1 • 10 -3 wt.%, oxygen ~ 0.02-0.03 wt.%)  in comparison with the pure vanadium has been studied.
