Hydrogen Induced Structure and Phase Transformation in 304L Stainless Steel
-
摘要: 利用X射線衍射方法,研究了304L不銹鋼中電解充氫過程和隨后時效過程中的氫致奧氏體結構變化和氫致馬氏體相變。結果表明,電解充氫可導致奧氏體晶格膨脹和馬氏體相變,α’相和ε相同時出現,并且在室溫時效過程中并不能消失。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.
