| 摘要: |
| 研究Cr和Sb对球铁组织和性能的影响。认为单独加入这2种元素不能保证铸态下使模数37mm的铸铁达到QT600－3性能，而通过Sb－Cr复合合金化可以达到此目的。原理分析表明Sb－Cr复合是较好的搭配。用推荐的加入量进行生产验证的结果表明效果良好。 |

| Abstract: |
| Based on the detailed investigation of the influence to microstructure and properties of ductile iron by Cr and Sb, it has been shown that neither Cr nor Sb promises a QT 600-3 property on module 37 mm castings expect Sb-Cr composite alloying. The analysis indicated that Cr and Sb are good couple in alloying. The as-cast QT 600-3 property can steadily reached by production testes. |
