| Abstract: | The effect of several inoculants on the properties of the gray cast iron used in cylinder body is investigated in this paper.The results show that tensile strength is about 300 MPa,and metallurgy quality is improved for the gray cast iron inoculated by using Re inoculants.While,the gray cast iron inoculated by using Sr inoculant has the best processability and the least sensibility of section hardness. |
