Influence of Hydrogen on Dislocation Structure in a Duplex Stainless Steel

摘要

The dislocation structure of specimens of aduplex stainless steel with precharged hydrogen hasbeen investigated by transmission electronmicroscopy.The result showed the hydrogen acti-vated dislocation source on phase boundaries offerrite/austenite and makes certain dislocations inaustenite grains move.The dislocation appearancesin each phase in specimens uncharged withhydrogen have been given for comparison.
