| Resumen: | This document gives guidelines for the measurement of hardmetal grain size by metallographic techniques only using optical or electron microscopy. It is intended for sintered WC/Co hardmetals (also called cemented carbides or cermets) containing primarily WC (de: Wolframcarbid, en: tungsten carbide) as the hard phase. It is also intended for measuring the grain size and distribution by the linear-intercept technique. |
