纯铁离子氮化后时效的x射线衍射分析

THE X-RAY DIFFRACTION ANALYSIS OF PURE IRON AGED AFTER ION-NITRIDING

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。

We have discovered by X-ray diffraction that the aging of commerical pure iron will lead to the phase transformation ε→α″→(?) after ion-nitriding. The e phase is of spinodal structure. The results provide the evidence for the age hardening of compound layer.
