DescriptionMartensitic transformation (MT) is a very common characteristic in many different types of alloys. Recently, it become very popular because the development of transformation induced plasticity steal or material. These material phase transformed as they been deformed. With high resolution transmission electron microscopy observation in MT progress, researchers find out there is a step shape interfaces between the different phase crystals. Hirth and Pond used new the concept of Topological Model (TM), which divide the dislocation arrays into lattice invariant deformation (LID) and disconnection, to simulate MT cryptography. It is critical to describe disconnection which is a new type of dislocation in martensitic because it can predict the motion of transformation. Ma and Pond used TM to simulate the martensite transformation of ferrite system and calculate LID and disconnections arrays with given crystal orientation from NW orientation to KS orientation. However, the solution is not consistency because Frank-Bilby equation have multiple solutions. In this work, we developed a tool to enumerate all possible results of dislocation arrays and calculate the dislocation energy based on these results. Then we sort them with respect strain energy from lowest to highest to find out the distribution of dislocation arrays that could happen on the interface during MT progress.
