Abstract

V-4Cr-4Ti alloys have been identified as the reference material for fusion reactor applications. One of the main issues of using them at elevated temperatures is their high affinity with gaseous elements. It is necessary to improve their oxidation and corrosion resistance, in order to use them in the various environments, such as vacuum leak and reaction with water. In this paper, V-based high Cr and Ti alloys were prepared and exposure tests in air and pressurized water were conducted to study the influence of Cr, Ti concentration on their oxidation and corrosion properties. After the oxidations in air, the weight gain was reduced as Cr concentration increased. The results of the tests in water showed weights of each alloy were reduced as corrosion time. The weight losses were significantly reduced as Cr concentration increased. It is concluded that addition of Cr is effective to reduce the weight change after corrosion particularly in water.
