Abstract

Natural rock salt was gamma irradiated at a dose rate of 8 multiplied by 10**6 rad/h for up to 1338 hours. Subsequent dissolution in water produced high pH solutions. The corrosion properties of ASTM Grade-12 titanium were evaluated in simulated alkaline rock salt brines. Uniform corrosion rates were enhanced compared to neutral solutions but crevice corrosion rates were retarded because of difficulties in obtaining high acidity in the crevice region. Hydrogen uptake was enhanced because of chemical dissolution of the oxide layer. On hydrogenation, tensile samples showed slow-strain-rate embrittlement. Stress corrosion cracking was not detected.
