| Abstract: | The making method of as-cast austenitic-bainitic ductile cast iron(ADI)and itsmatrix structure and mechanical properties are introduced.The cavitation erosion resistanceof ADI is also investigated.The experiment results shows that the cavitation erosion resis-tance of ADI is more than 3 times higher than that of general ductile cast iron.NI,Mo,Cuand B play an important role in the matrix structure,mechanical properties,and the cavitationresistance.The austenitic stticture has a good cavition erosion resistance. |
