适用范围：This par of EN 623 specifies a manual method of making measurements for the determination of volume fraction ofmajor phases in 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 true 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,The method applies to ceramics with one or more distinct secondary phases, such as found in Al
