An advanced approach to reconstructing parent orientation maps in the case of approximate orientation relations: Application to steels

Reconstructions allow the evaluation of the microtexture before phase transformation from that measured by EBSD after phase transformation. Even though they have been applied successfully to titanium alloys and other materials, their application to reconstruction of austenite in steels requires care. This paper details first a new approach to crystallographic reconstruction, which has been designed to meet the necessary requirements in steels. This approach is then validated in two low-carbon steels. The goal is to fix the potential and limits of crystallographic reconstruction when applied to steels. Important recommendations are made to ensure accurate reconstruction.
