  The determination of orientation relationships in dual or multi-phase
materials is very important in the field of interface engineering for the
design of materials with tailored properties. In this work, a code is developed
for the automated and statistical analysis of the orientation relationship of
electron backscatter diffraction data. On the example of Fe-Ni-(Si)-C alloys
containing lenticular martensite and retained austenite, the code is applied
and it is shown that the orientation relationship (OR) corresponds to the
Greninger-Troiano OR and that a statistically reliable investigation of the OR
between the retained austenite and the related martensite variants is feasible
using the code developed in this study.
