摘要：

The crystallography of phase transformation is an important issue for studying metallic alloys.Here,we demonstrate an abnormal orientation relation between face-centered cubic（fcc） and hexagonal closepacked（hcp） phases due to the intersection of two ε;-martensite variants in a high manganese steel.The corresponding crystallogra phic cha racteristics,including invariant line,habit plane and atomic steps,have been characterized by transmission electron micro scopy and the quasi-O-line model.In addition,the models of phase transfo rmation about the intersection are proposed based on transmission mechanisms of dislocations.Our findings enrich the theories of phase transformation and implicate the possibility to fabricate stro nger and tougher steel.
