摘要：
Hot corrosion behavior of an Al2O3/YAG eutectic composite in molten V2O5 at 800degreesC and 1500degreesC has been investigated. This composite showed a more stable behavior than polycrystals due to its peculiar microstructure. The surface reaction product Of YVO4 also prevented the penetration of molten V2O5. The higher testing temperature resulted in less corrosion, due to V2O5 vaporization.
