Scope
This part of ISO 13383 describes manual measurement methods for determining the grain size of advanced ceramics using photomicrographs of polished and etched samples. The methods described in this part do not give the true mean grain diameter, but rather a slightly smaller value depending on the method used to analyze a two-dimensional sample cross section. The connection with the true grain dimensions depends on the grain shape and the degree of anisotropy of the microstructure. This part contains two methods, Method A and Method B. Method A is the method for determining the average cutting line length (line cutting method). Method A1 applies to single-phase ceramic materials with a crystalline main phase and a glassy grain boundary phase with a volume fraction of at most approximately 5%, for which counting the intersection points is sufficient. Method A2 applies to ceramic materials with a volume fraction of over approximately 5% pores or secondary phases or to ceramic materials with more than one crystalline main phase, for which individual cutting line lengths are measured, which can optionally also be used to determine the grain size distribution. In the latter method, pores or phases can be distinguished and for each the average grain size, determined from the cutting line length, can be determined separately. NOTE A method for determining the volume fraction(s) of the secondary phase(s) can be found in ISO 13383-2; In borderline cases it offers decision options as to whether procedure A1 or procedure A2 should be used. Method B is the method for determining the mean equivalent circle diameter, which can be used for all ceramic materials with or without a secondary phase. This method may also be used to determine the aspect ratio of the grains and to determine the grain size distribution. Some users of this part of ISO 13383 may wish to apply automatic or semi-automatic image analysis to the micrographs or to directly displayed micrographs. The use of these analytical procedures is permitted under this Part provided that technology equivalent to manual procedures is used (see Sections 4 and 8.4).
