GB/T 26656-2011
AbolishedMetallographic test for compacted(vermicular )graphite cast irons
蠕墨铸铁金相检验
Application Summary AI generated
This standard specifies the metallographic testing methods for compacted (vermicular) graphite cast irons, including the classification, evaluation, and measurement of graphite morphology and matrix structure. It is applied in the metallurgy and foundry industries for quality control and material characterization of components such as engine blocks, brake drums, and exhaust manifolds, where the material's mechanical and thermal properties are critical. The standard is used during production inspection and failure analysis to ensure compliance with specified microstructural requirements.
