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.
