| Abstract: | On the basis of study nondestructive detecting samples of spheroidal graphite cast iron using sonic resonant method, nodularity and matrix structure of ductile iron camshafts have been further in-vestigated in this paper. The results showed that the sonic resonant method was suitable for 100% mea-suring on the production line. |
