ASTM B657 – Standard Guide for Metallographic Identification of Microstructure in Cemented Carbides
Significance and Use
4.1 The microstructure of a cemented carbide affects the material’s mechanical and physical properties. This guide is not intended to be used as a specification for carbide grades. Producers and users may use the microstructural information as a guide in developing their own specifications.
1.1 This guide covers apparatus and procedures for the metallographic identification of microstructures in cemented carbides.
