Characterization of cast iron using ultrasonic testing

This paper presents an overview of possibility of the cast iron characterization using ultrasonic testing that could eliminate most of the disadvantages of the metallographic method, but its usage is limited by the fact that velocity and attenuation of ultrasonic wave depend on technological singularities of cast iron production. Characterization of microstructural features and mechanical properties of cast iron is based on the ultrasonic testing parameters, primarily on ultrasonic wave velocity, which depends on the elastic modulus and density of the cast iron.
