标准摘要
[中文适用范围]： ISO 4499 的本部分提供了使用金相技术（仅使用光学显微镜或电子显微镜）测量 Ti(C,N) 基硬质合金和含有额外立方碳化物的 WC/C 硬质合金的微观结构特征的指南。本部分适用于主要含有无机碳化物和氮化物作为硬质相的相关硬质合金（也称为硬质合金或金属陶瓷）。本部分还适用于通过线性截距技术测量相的尺寸和分布。 [外文原描述]： ISO 4499-3:2016 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.
