In this work, the observations of the fracture surface after standard tensile tests of several kinds of spheroidal cast irons, ferritic and austempered ductile irons, have been carried out by means of scanning electron microscopy. The local crack path in the area of graphite (G)/matrix (M) interface has been analyzed as affected by a matrix phase composition and the austempering treatment parameters. The obtained results allowed identifying some determination factors for debonding mode at the G/M interface and their role in a final damage mechanism. Some microstructural details in the microregions composed of graphite and matrix showed that the G–M debonding mode in the separation area of the G/M interface seems to be controlled by macroscopic properties of the alloy and by the morphology of G/M interface. On the other hand, the internal destruction of graphite nodule has been mainly determined by a structure and anisotropy of graphite crystal lattice.

球墨铸铁损伤的微观机制的微观方法。

在这项工作中，已经通过扫描电子显微镜对几种球墨铸铁，铁素体和奥氏体球墨铸铁进行了标准拉伸试验后对断裂表面的观察。分析了石墨（G）/基体（M）界面区域的局部裂纹路径，受基体相组成和奥氏体回火处理参数的影响。获得的结果允许确定一些决定因素，以决定G / M界面处的剥离模式及其在最终损伤机制中的作用。由石墨和基体组成的微观区域中的一些微观结构细节表明，G / M界面分离区域中的GM脱键模式似乎受合金的宏观性能和G / M界面形态的控制。另一方面，
