Abstract: The crystallographic features of pearlite were investigated by experiments and edge-to-edge matching principle. Two new orientation relationships between ferrite and cementite were determinated by selected area electron diffraction and then explained by our modified edge-to-edge matching method. The  consistence of the experimental results with theoretical prediction confirms the practicability of the modified edge-to-edge matching model.
