Hydrogen diffusivity and solubility in Inconel 600 were determined with a gas-absorption method using tritiated hydrogen gas in a temperature range from 573 K to 973 K. The temperature dependence of diffusivity D and solubility S were obtained as,D (cm2s−1) = 1.3 x 10−2 exp(−50.6/(RT / kJ)),S (cm3(NTP)cm−3Pa−0.5) = 4.7 x 10−3 exp(−11.7 /(RT / kJ)).
