| Abstract: | The stability of mechanical properties for Cu-Mo alloyed austempered ductile iron (ADI) was studied. The results can be compared to the finnish specification of Kymenite9805 under 95% probability. The casting defects, graphite morphology and matrix structure can significantly affect the mechanical properties of the Cu-Mo alloyed ADI. The basic principles of quality control are presented. |
