合金渗碳体

结果表明，高锰钢基复合材料的显微组织由TiC颗粒，奥氏体和合金渗碳体组成。

The results show that microstructure of high manganese steel matrix composite is made of TiC particles , austenite and alloy cementite .

对变质铸态中锰钢进行热力学计算、晶体结构分析，透射电镜与电子探针研究，发现SiO2完全可以作为层片状共生共晶体（共晶两相为奥氏体与合金渗碳体）的非自发核心。

By calculation of thermodynamics , analysis of crystal structure and study of TEM and eletron probe , it is first discovered that SiO_2 can be acted as one of the heterogeneous nuclei for lamellar intergrowth eutectic ( austenite and cementite ) crystallizing in modified as-cast medium manganese steel .

一个是碳化物（类似于渗碳体或合金渗碳体）。

The another is carbide ( similarly cementite or alloy cenentite ) .

结果表明Ni&P合金在渗碳体基体表面和晶界上优先沉积，沉积初期的镀层分布是不均匀的。

The results showed that Ni - P alloy prefer to deposit on the surface and crystal boundary of cementite matrix .
