eutectic cementite

According to the results of DSC and microstructure analysis, the more Al content, the higher melting point of the alloy, but the more α phase dendrites, the less eutectic cementite.

从差示扫描量热分析和显微组织得出：随含铝量的增加，合金的熔点提高，α相枝晶增多，晶间的共晶体减少。

Study on Relation between the Morphology of Eutectic Cementite and Lower Temperature Graphitization of Malleable Cast Iron

共晶渗碳体形态与可锻铸铁低温石墨化的关系及分析

Results indicated that microstructure of the ZSF alloy consists of austenite and eutectic cementite.

结果表明,ZSF合金的显微组织是奥氏体+共晶碳化物.

According to mathematical statistics treatment of data measured from total 2500 fields, it is shown that there are apparent differences between the morphology of eutectic cementite in the two kinds of aforementioned samples.

用数理统计分析了2500个视场的测量结果表明，共晶渗碳体的分布形态在上述两种试样中存在明显差异。

Effect of Si on the Microstructure of Eutectic Cementite in As cast Malleable Cast Iron

硅对可锻铸铁共晶渗碳体显微结构的影响

The results showed: in the as-cast white iron there was the enrichment of silicon between the eutectic cementite and pearlite.

结果表明：硅在共晶渗碳体和珠光体界面处富集，少量硅进入共晶渗碳体中；

The alloying elements Ti and C can form TiC directly in the melt which acts as nucleus of cementite and causes both primary and eutectic cementite granulated and refined. So the cementite network in this steel can be eliminated.

Ti和C可以直接在液相中反应形成TiC，并可作为渗碳体的结晶核心，使一次渗碳体和共晶渗碳体发生粒化和细化，从而避免连续网状碳化物的形成。
