ULTRASONIC INSPECTION OF GRAIN SIZE IN THE MATERIALS FOR RAILWAY WHEEL SETS

This work outlines the present theory of attenuation of the ultrasonic waves, particularly the theory of scattering, and describes the measurement of attenuation in metals. Experiments were carried out to measure the attenuation of samples with different grain size taken from materials for railway wheel sets; in these experiments the pulse echo method, with elimination of the effect of the reflexion factor, was applied. The article presents the relation between the overall attenuation coefficient and its scattering component, the grain size and frequency. On the basis of our measurements and an analysis of the obtained results, two methods of evaluation of the structure of railway materials by ultrasonic inspection were derived.
