EBSD mapping was used for phase analysis of multi-phase steels. Some products austenite decomposition could be discriminated using a range grain-average functions and properties derived from the map data. In DP steels, martensite extracted ferrite matrix average band contrast or set geographic information. Bainite in TRIP steel identified with local variations orientation inside grain. As proposed method reproduced map, visual confirmation result additional analyses were possible.
