Hardmetals - Metallographic determination of microstructure - Part 3: Measurement of microstructural features in Ti (C, N) and WC/cubic carbide based hardmetals (ISO 4499-3:2016)
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.

L'ISO 4499-3:2016 donne des lignes directrices relatives à la mesure des caractéristiques des microstructures des métaux-durs à base de carbures Ti(C,N) et de métaux-durs WC/Co contenant des carbures cubiques supplémentaires selon des techniques métallographiques utilisant uniquement un microscope optique ou électronique. Elle est destinée aux métaux-durs frittés (également appelés carbures cémentés ou cermets) contenant principalement des carbures et nitrures inorganiques sous la forme d'une phase dure. Elle est également destinée au mesurage de la taille des phases et de la distribution au moyen de la technique d'interception linéaire.

Ta del standarda ISO 4499 podaja navodila za merjenje mikrostrukturnih značilnosti v trdinah na osnovi Ti (C, N) in WC/kubičnega karbida, ki vsebujejo dodatne kubične karbide, na podlagi metalografskih tehnik, ki uporabljajo le optično mikroskopijo ali mikroskopijo elektronov. Uporablja se za sintrane trdine (imenovane tudi cementirani karbidi ali cermeti), ki v trdi fazi vsebujejo pretežno anorganske karbide in nitride. Namenjen je tudi merjenju velikosti in distribucije faze s tehniko linearnega prestrezanja.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information.
The committee responsible for this document is ISO/TC 119, Powder metallurgy, Subcommittee SC 4,
Sampling and testing methods for hardmetals.
ISO 4499 consists of the following parts, under the general title Hardmetals — Metallographic

Introduction
This part of ISO 4499 essentially covers the following topics:
— materials types and phases to be measured including the following:
— Ti(C, N) cermets;
— WC/Cubic carbide hardmetals;
— preparation methods to highlight differences between conventional WC/Co hardmetals and
materials containing cubic phases;
— linear analysis techniques to acquire sufficient statistically meaningful data for phase quantification;
— analysis method to calculate representative average values;
