Owing to inter-phase orientation relationship, EBSD analysis of martensitic or bainitic steel enables reconstruction of prior grains. Thus, assessment of the treatment conditions remains possible even if the chemical etching cannot properly reveal the parent structure. However, such an approach is hardly applicable to the industrial modes of multi-pass rolling. Unlike a single thickness reduction, small strains per pass followed by a kind of annealing in inter-pass pauses cause specific mechanisms of austenite recrystallization so that the latter becomes difficult to be assessed in morphological terms. At the same time, the textural analysis enables estimation of the parent state using whether the texture of reconstructed austenite or the measured transformation texture. When tested on low carbon bainitic steel, both methods lead to close estimates of the parent texture and thus support each other.
