AbolishedHardmetals—Metallographic determination of porosity and uncombined carbon
硬质合金 孔隙度和非化合碳的金相测定
Application Summary AI generated
This standard specifies the metallographic methods for determining the porosity and uncombined (free) carbon content in hardmetals (cemented carbides). It is applied in the quality control and material analysis of cutting tools, wear parts, and mining components made from hardmetals, ensuring their microstructure meets performance requirements. The standard is used by manufacturers and testing laboratories to evaluate and classify the internal defects of sintered carbide products.
