Guide for Metallographic Identification of Microstructure in Cemented Carbides
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers apparatus and procedures for the metallographic determination of microstructures in cemented tungsten carbides.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Precautions applying to use of hazardous laboratory chemicals should be observed for chemicals specified in Table 1.
Significance and Use
The microstructure of a cemented carbide affects the material’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.
