用x射线衍射发现,工业纯铁氮化后时效将引起ε→α″→γ′转变,ε相具有调幅结构。该结果为化合物层时效强化找到了理论依据。
It is found by X-ray diffraction that the aging of industrial pure iron after nitriding will lead to the transformation of ε → α "→ γ ’and the ε phase has the amplitude modulation structure. This result provides a theoretical basis for the aging enhancement of the compound layer.
