Abstract
In the present paper, the influence of grain morphology on the textures of multiphase steels measured after phase transformation is investigated. Especially, it is shown that the presence of very elongated grains in the product phase can strongly influence the classical quantitative determination of the texture of this phase from surface measurements (in X-ray diffraction or EBSD). Thus, a method is proposed to deduce the “real” texture from the “apparent” one, measured within a plane. It is then shown that for the investigated multiphase steel, for which phase transformation has occurred either from deformed or recrystallized austenite, this correction provides a very good quantitative agreement between corrected experimental product (ferrite) textures and those obtained from the parent (austenite) phase, assuming a KS or slightly different orientation relationship, without considering any variant selection.
