By employingthis method the hydrogen trapping effect can be eliminated completely and the diffusivity canbe measured more accurately. The permiation experiment of Armoc Fe was performed and thediffusivity of hydrogen in the lattice of α-Fe between 290K and 350K has been given asD_0=5.12×10~(-8)exp(-4320/RT) (m~2/s) Key words:  diffusivity      hydrogen      electrochemical permeation      armoc Fe      hydrogen trapping      Received:  18 February 1988      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1988/V24/I2/218 1 Devanathan M A V, Stachurski Z.
