3-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 section s were obtained through repeated metallographic polishing and imaging and interpolation was done using the 'watershed' algorithm, Electron b ackscatter 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.
