Abstract
Hot-dip galvannealed coatings of two Mn-Si TRIP steels have been characterized by transmission electron microscopy to study the crystallographic orientation relationships between the α-Fe and Î1 phases, the Î1 and Î2 phases, as well as the Î2 and δ phases. Both the α-Fe/Î1 phases and the Î1/Î2 phases were found to exhibit a cube-on-cube orientation relationship. The orientation relationship at the Î2/δ interface was identified to be 112¯0δ//[011]Î2 and (0002) δ//111¯Î2. The interfaces of Î2/δ and Î1/Î2 are basically the close-packed plane of each phase. The nucleation of Î2 phase between the δ and Î1 phases was discussed by the heterogeneous nucleation theory based on the orientation relationships and the interfaces.
