AbstractTwo kinds of gamma'-Fe4N nitrides precipitated from the diffusion layer of ion-nitrided pure iron during the furnace cooling process. One kind is full of finely spaced parallel striations, which are identified as stocking faults, while the other does not have such parallel stacking faults. alpha " --> gamma' nitride transformation was directly observed in the diffusion layer, which gives definite evidence for the in situ nucleation of gamma'-Fe4N on alpha " -Fe16N2 nitride. The interior of the gamma'-Fe4N nitride transformed from alpha " -Fe16N2 nitride has parallel stacking faults. This nitride transformation was discussed according to their crystal structures. There is a orientation relationship of (1 (1) over bar1)(gamma') // (1<(1)over bar >0)(alpha "), [110](gamma') // [111](alpha ") during the transformation.
