Abstract

Abstract

Hydrogen induced austenite structure transformation and martensite transformation in 304L stainless steel during hydrogen charging and aging were studied by X-ray diffraction. The results showed that hydrogen charging could induce austenite lattice expansion and martensite transformation.α' phase and ε phase appeared in the same time, and they did not disappear after aging at room temperature.
