Bainitic steel with the reconstruction of the austenitic grains.
A computer program called ARPGE automatically reconstructs the parent grains from EBSD data obtained on phase transition materials, with or without residual parent phase. The misorientations between the daughter grains are identified with operators, the daughter grains are identified with indexed variants, the orientations of the parent grains are determined and some statistics on the variants and operators can be established. Some examples with martensitic transformations in steels and titanium alloys have been treated. Variant selection phenomena have been revealed.
