应用电子衍衬技术和扫描电镜等手段，对共析珠光体轨钢的微观结构和断裂过程，进行了观察和分析。
The microstructure and fracture process of an eutectoid pearlitic steel have been observation and analysed by means of electron-diffraction-contrast technique and SEM.
高于此点，由于超过共析点钢完全由珠光体和退火状态的渗碳体组成，硬度增加并不多。
Above this point the hardness can be increased only slightly, because steels above the eutectoid point are made up entirely of pearlite and cementite in the annealed state.
作为结果的组织结构是初步的共析铁素体(在共析反应前的铁素体)和部分珠光体的混合物。
The resulting structure is a mixture of primary or pro-eutectoid ferrite (ferrite that formed above the eutectoid reaction) and regions of pearlite.
