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;
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。
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。
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。
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. 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。
