含Cr13%高铬铸铁的试验研究

Study on High chromium Cast Iron Containing 13%Cr

在试验的基础上研究了含Ｃｒ１３％的高铬铸铁的力学性能和组织特点，发现含硅量和变质处理对不同基体的高铬铸铁具有相似的影响规律；根据ＦｅＣＣｒ三元相图对Ｃｒ１３％高铬铸铁的凝固过程进行了分析，从一个新的角度揭示了铸造条件、含硅量和变质质处理对高铬铸铁性能和组织的影响机理。

The mechanical properties and microstructure of high chromium cast iron containing 13% Cr were studied on the basis of experiments, and it was found that silicon and inoculations influenced the high chromium cast iron with different microstructures in almost the same way. The solidification of Cr13% was also studied with Fe C Cr equilibrium diagram, and the mechanism of effects of processings on high chromium cast iron was explained in a new way.
