氢致304L不锈钢晶体结构变化与相变

Hydrogen Induced Structure and Phase Transformation in 304L Stainless Steel

利用X射线衍射方法,研究了304L不锈钢中电解充氢过程和随后时效过程中的氢致奥氏体结构变化和氢致马氏体相变。结果表明,电解充氢可导致奥氏体晶格膨胀和马氏体相变,α’相和ε相同时出现,并且在室温时效过程中并不能消失。

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 s phase appeared in the same time, and they did not disappear after aging at room temperature.
