摘要：
This article presents the acoustic characteristics of rails made of St90PA steel before installation in a track and after ten years of use. The Kaiser and Bauschinger effects were studied, as well as the effect of aging on the acoustic activity of the material. The acoustic emission method was used to signal the onset of fatigue cracking.
