Overview
This standard gives guidelines for the measurement of microstructural features in Ti(C,N) based hardmetals and WC/Co hardmetals that contain additional cubic carbides by metallographic techniques only using optical or electron microscopy. It is intended for sintered hardmetals (also called cemented carbides or cermets) containing primarily inorganic carbides and nitrides as the hard phase. It is also intended for measuring the phase size and distribution by the linear intercept technique. This document (EN ISO 4499-3:2016) has been prepared by Technical Committee ISO/TC 119 "Powder metallurgy", Subcommittee SC 4 "Sampling and testing methods for hardmetals". The responsible national standards committee is Working Committee NA 145-01-04 AA "Sampling and testing methods for hardmetals" ("Sampling and testing methods for hardmetals") at DIN Standards Committee Technology of Materials (NWT).
