Three-dimensional reconstruction of Widmanstatten plates in Fe-12.3Mn-0.8C

The three-dimensional reconstruction of serial sections is applied to examine Widmanstatten plates in a high-manganese steel, Serial sections were obtained through repeated metallographic polishing and imaging and interpolation was done using the 'watershed' algorithm, Electron backscatter diffraction was used to determine grain misorientations and cementite:austenite orientation relationships, This technique yields a unique combination of information concerning crystallography and the three-dimensional development of a solid body.
