Hardmetals - Metallographic determination of microstructure - Part 2: Measurement of WC grain size

DS/EN ISO 4499-2-2010 发布历史

This part of ISO 4499 gives guidelines for the measurement of hardmetal grain size by metallographictechniques only using optical or electron microscopy. It is intended for sintered WC/Co hardmetals (also called cemented carbides or cermets) containing primarily WC as the hard phase. It is also intended for measuring the grain size and distribution by the linear-intercept technique.This part of ISO 4499 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;. repo
