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.
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。

The eutectoid decomposition is a self organization process, which is characterized by the integrated mechanism that ferrite and cementite acted as prevenient phase alternatively.
共析分解是个自组织过程，具有铁素体和渗碳体互为领先相的整合机制。
