摘要：

The effect of different factors on the ultrasonic wave velocity is considered. These factors depend on the rail fabrication technology and the metal structure. Individual parameters of nonmetallic inclusions with the strongest effect on the wave propagation velocity are distinguished. The relation between the ultrasonic wave velocity and the nonmetallic inclusion content in currently produced rails and their mechanical characteristics is analyzed.
