摘要:

本文以正火态ZGD410-700牌号为例,做出合格金相F + P及不同级别的铸态残留非正常组织,分别进行性能、金相、硬度及冲击性能测试,结果表明:非正常组织对抗拉、延伸率无影响;硬度略高于合格F + P;明显降低材料的冲击性能。

This paper takes ZGD410-700 as an example. Qualified F + P microstructure and different levels of remaining casting abnormal structure are made following with property, microstructure, hardness and impact property testing. The result shows that: abnormal structure has no effect on strength of extension and elongation, also has higher hardness and lower impact property than qualified structure.
