ActiveHardmetals—Palmqvist toughness test
硬质合金 巴氏韧性试验
Application Summary AI generated
This standard specifies the method for determining the fracture toughness of hardmetals (cemented carbides) using the Palmqvist crack indentation technique. It is applied in the metallurgy and materials testing industry to evaluate the resistance of hardmetal products, such as cutting tools, wear parts, and mining inserts, to crack propagation under indentation loads. The test is particularly relevant for quality control and material development in manufacturing sectors that rely on cemented carbide components.
