Phase discrimination

 

EBSD can be used to discriminate crystallographically dissimilar phases by comparing the interplanar angles measured from the diffraction pattern, with calculated angles from a set of candidate phases and selecting the best fit.   Figure 8 shows the separation of the austenite and ferrite phases in a duplex stainless steel.  Austenite is face centered cubic, and ferrite is body centered cubic, and the phases can not be distinguished by X-ray microanalysis.   The phase map shows that 38.6% of the sampled area is ferrite and 60.7% is austenite.  The crystal orientation maps also reveal the constituent grains in the two phases.
