The continuity of the eutectoid cementite lamellae was reduced when the ferrite sub-lamellae were incorporated. The planar indices of the ferrite sub-lamellae are found usually close to {211}F.Some contrast fringes observed at the cementite/ferrite interface were analyzed and compared with the sub-lamellae in the eutectoid cementite. The formation mechanism of ferrite sub-lamellae in eutectoid cementite was also discussed.
