A martensitic iron (courtesy of J. Michael). (a) EBSD orientation map of the martensitic grains and (b) corresponding pole figure. ARPGE finds only one austenitic grain, whose orientation is indicated by the red circles superimposed on the pole figure. (c) According to that orientation, theoretical pole figure of the 24 variants (blue spots) in a Kurdjumov–Sachs orientation relationship with the parent crystal (red spots). |
