| Subject of the standard: | This document gives guidelines for the measurement of hardmetal grain size by metallographic techniques only using optical or electron microscopy. It is intended for WC/Co hardmetals (also called cemented carbides or cermets) containing primarily tungsten carbide (WC[1]) as the hard phase. It is also intended for measuring the grain size and distribution by the linear-intercept technique. This document essentially covers four main topics: — calibration of microscopes, to underpin the accuracy of measurements; — linear analysis techniques, to acquire sufficient statistically meaningful data; — analysis methods, to calculate representative average values; — reporting, to comply with modern quality requirements. This document is supported by a measurement case study to illustrate the recommended techniques (see Annex A). |
