Abstract

The deformation microstructures associated with crack propagation in a hydrogen-charged ferritic steel were examined. A decrease in the dislocation density and fragmentation of the matrix were observed to take place. The location of the halo rings suggested that the atomic configuration in the amorphous phase was associated with some lattice expansion.
