Abstract
The influence of hydrogen on the deformation ahead of the crack tip an d the crack propagation were observed and studied in situ under transm ission electron microscopy with dynamic tensile deformation for bridge steel, The results show that hydrogen can promote local plastic defor mation ahead of the crack tip and change the mode of crack propagation so that the crack will propagate in a zigzag path.
