    • Abstract


      The room temperature diffusivity of hydrogen in a fully B2 ordered iron aluminide of composition Fe-35·8 Al was estimated from the experimental hydrogen depth profile to be 2·38×10−15m2/s. The mathematical procedure utilized for data analysis has been described. The estimated diffusivity is a lower bound value due to surface trapping effects.
