蠕虫状石墨和球状石墨共存是蠕墨铸铁金相组织的主要特征。由于蠕虫状石墨和球状石墨在形貌特征、共晶团结构及大小均不同,因而蠕墨铸铁中蠕虫状石墨和球状石墨所占的比例将会影响各种性能。本文是在光学金相分析的基础上,研究蠕墨铸铁
The coexistence of vermicular graphite and spherical graphite is the main feature of compacted graphite cast iron microstructure. As vermicular graphite and spherical graphite in morphology, eutectic structure and size are different, so vermicular graphite and graphite in the proportion of graphite spherical graphite will affect a variety of performance. This article is based on the optical metallographic analysis of vermicular graphite iron
