diagrams 1 Scope This part of GB/T 34474 specifies the method for determining the banded structure of hypoeutectic steel (including ferrite banding and class II structure banding) using comparison method. This part is applicable to the determination of banded structure of plastically deformed hypoeutectoid steel, while not applicable to the determination of banded carbide of hypereutectoid steel. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 13298 Inspection methods of microstructure for metals GB/T 30067 Standard terminology relating to metallography 3 Terms and definitions For the purposes of this document, the terms and definitions given in GS/T 30067 and the following apply. 3.1 banded structure alternating microstructure banding parallel to the processing direction finally formed through deformation elongation in microsegregation area during steel plasticity processing Note: herein it refers to ferrite and class II structure banding. 3.2 class II structure banding banding composed of single or multiple structures (except ferrite), including pearlite, bainite and other non-equilibrium structures Note: where determined, they participate in the rating as a structure class. 3.3 continuous banding banding of the same class appearing in a view field, wherein, grains are separated only by grain boundaries and no structure of other class appears 4 General and application
