30、raphs 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 true phase volume fractions are equivalent to area fractions on a randomly cut cross-section according to stereological princip

31、les.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 more distinct secondary phases, such as found in Al2O3/ZrO2, Si/SiC, or Al2O3/SiCw.If the test material contains discrete pore

32、s, 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 genuine pores.NOTE 3 If the material contains more than about 20 % porosity, there is a strong risk that the microstructure will

33、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 of less than 0,05 are subject to considerable error and potential scatter in results. A larger number of micrographs than the

34、 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 make a reasonable estimate of glassy phase content, the glass material between crystalline grains should be readily observabl

35、e, 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 are seldom homogeneous, and the phase contents can vary from micrograph to micrograph. It is essential to survey a sufficient

36、ly 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 that the selected regions of a prepared cross-section are statistically representative of the whole sampled section.Some use
