27、n) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep
28、resented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards ar
29、e drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internationa
30、l Standard requires approval by at least 75 % of the member bodies casting a vote.ISO 13383-2 was prepared by Technical Committee ISO/TC 206, Fine ceramics.ISO 13383 consists of the following parts, under the general title Fine ceramics (advanced ceramics, advanced technical ceramics) Microstructura
31、l characterization: Part 1: Determination of grain size and size distribution Part 2: Determination of phase volume fraction by evaluation of micrographs4EN ISO 13383 2:2016 (E) -DIN EN ISO 13383-2:2016-08 1 ScopeThis part of ISO 13383 specifies a manual method of making measurements for the determi
32、nation of the volume fraction of major phases in fine ceramics (advanced ceramics, advanced technical ceramics) using micrographs of polished and etched sections, overlaying a square grid of lines, and counting the number of intersections lying over each phase.NOTE 1 This method assumes that the tru
33、e phase volume fractions are equivalent to area fractions on a randomly cut cross-section according to stereological principles.NOTE 2 Guidelines for polishing and etching of advanced technical ceramics can be found in Annexes A and B of ISO 13383-1:2012.The method applies to ceramics with one or mo
34、re distinct secondary phases, such as found in Al2O3/ZrO2, Si/SiC, or Al2O3/SiCw.If the test material contains discrete pores, these are to be treated as a secondary phase for the purpose of this method, provided that there is no evidence of grain pluck-out during polishing being confused with genui
35、ne pores.NOTE 3 If the material contains more than about 20 % porosity, there is a strong risk that the microstructure will be damaged during the polishing process, and measurement of the volume fraction of pores may become misleading. Secondary phase volume fractions or porosity present at levels o
36、f less than 0,05 are subject to considerable error and potential scatter in results. A larger number of micrographs than the minimum of three is normally needed to improve the consistency and accuracy of the results.NOTE 4 Many ceramics contain small amounts of secondary glassy phases. In order to m
37、ake a reasonable estimate of glassy phase content, the glass material between crystalline grains should be readily observable, and thus should be at least 0,5 m in width. The method in this part of ISO 13383 is not considered appropriate for narrow glassy films around grains.NOTE 5 Microstructures a
38、re seldom homogeneous, and the phase contents can vary from micrograph to micrograph. It is essential to survey a sufficiently wide area of the prepared section to ensure that those areas selected for evaluation are representative, and do not contain eye-catching irregularities. This method assumes
39、that the selected regions of a prepared cross-section are statistically representative of the whole sampled section.Some users of this part of ISO 13383 may wish to apply automatic or semiautomatic image analysis to micrographs or directly captured microstructural images. This is currently outside t
40、he scope of this part, but some guidelines are given in Annex A.2 Normative referencesThe 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

43、able phases other than a primary crystalline phase in a materialNOTE A secondary phase can be in the form of discrete grains, or as a continuous phase surrounding some or all of the major phase grains. For the purposes of this part of ISO 13383, porosity may be treated as a secondary phase.4 Apparat
44、us4.1 Sectioning equipmentAny suitable method may be used for preparing the test section from the item under investigation. If a diamond-bladed cut-off saw is employed, it is recommended that the grit size should not exceed 150 m.NOTE This grit size is designated as D151 according to ISO 6106 5.4.2
45、Mounting equipmentSuitable metallurgical mounting equipment and media for providing firm gripping of the test piece for polishing.4.3 Grinding and polishing equipmentSuitable grinding and polishing equipment, employing diamond abrasive media.NOTE A sequence of abrasives and techniques recommended fo
46、r polishing are given in Annex A of ISO 13383-1:2012.4.4 MicroscopeAn optical or scanning electron microscope with photomicrographic facilities.NOTE Although the true magnification of the image is unimportant for making the measurement of the volume fraction, it is advised that a reference graticule
47、 may be used to determine magnification in an optical microscope, or a reference grid or latex spheres may be used for calibration of magnification in a scanning electron microscope, and as a check on the homogeneity of magnification across the field of view.An optical microscope is additionally req
48、uired for assessing the quality of polishing (see 5.4).4.5 Transparent gridTransparent square grid on, e.g. acetate film, and with line thickness not exceeding 0,1 mm.NOTE 1 The grid spacing selected is not critical, but may conveniently be between 3 mm and 15 mm to minimize eyestrain. However, it i
49、s necessary that consideration of the requirements of 6.3 is taken into account.6EN ISO 13383 2:2016 (E) -DIN EN ISO 13383-2:2016-08 NOTE 2 A suitable grid may be prepared as a computer plot with sufficient accuracy of line spacing for the purposes of this part of ISO 13383.5 Test piece preparation5.1 SamplingThe test pieces shall be sampled in a manner subject to agreement between parties.NOTE Guidance on this issue may be found in EN 1006 (see Bibliography
