Abstract

Abstract

The effect of hydrogen on the cracking of type 310 stainless steel was studied by TEM in situ observation of hydrogen-charged specimens and comparison with the hydrogen-free specimens.The results show that the effect of hydrogen on the change from ductile to brittle is to prevent nano cracks in DFZs from blunting into voids.
- hydrogen-induced brittle crack,
- microcrack,
- TEM in situ observation dislocation,
- dislocation free zone,
- steel 310
