摘 要：<正> In present work,Fe-3%Si alloy specimens with various degrees of cold working and various grainsizes were chosen to determine the effect of cold working and grain sizes on the hydrogendiffusivities by electrochemical permeation method and the mechanism of hydrogen trapping by dis-ocations and grain boundaries is discussed.
