GENERAL METHOD OF HABIT PLANE DETERMINATION IN BAINITIC STEELS .2. HABIT PLANE DETERMINATION OF BAINITE

A new method is given for the determination of the bainite habit plane in specimens of a 35NiCr18 steel. The transformation of this steel is complete on cooling to room temperature. That is, no austenite is retained in the structure. Therefore, the new method is based on the orientation determination of the austenite prior to the bainite transformation using non-parallel {111} twin intersections, as described in Part I. Results of measurements of the bainite habit plane are reported. These results are compared with those obtained from two-surface analyses employed to the same bainite plates. © 1978.
