| Abstract: | Improving the effectiveness of nondestructive testing of railway rolling stock’s wheel-pair components during their manufacturing and repair is considered. The results of metallographic studies of PY-1 and PY-1III solid-rolled wheels and axles, analysis of the operating specifications, and experimental studies of the optimal methods of nondestructive testing are included. |
